Example Question #2231 : Algebra 1
Find the solution set to the compound inequality:
Solve each of these two inequalities separately:
, or in interval form,
(Note the flipping of the inequality because of the division by a negative number.)
, or in interval form,
The question asks about the intersection of the two intervals:
The intersection is the area of the number line that the two sets share, or .
Example Question #18 : How To Find The Solution To An Inequality With Division
Solve the following inequality.
To solve this inequality, move all the terms with on one side and all other terms on the other side, then solve for x.
Example Question #19 : How To Find The Solution To An Inequality With Division
Solve the inequality
.
Inequalities are treated as equalities when it comes to balancing, with the exception of division by a negative number (then flip the greater/less than symbol).
The question is asking for the solved inequality isolating . Combine like terms across sides by adding or subtracting same value to both sides.
Example Question #20 : How To Find The Solution To An Inequality With Division
Solve the inequality.
Use the properties of inequalities to balance the inequality and isolate .
First subtract three from both sides.
Next, divide by four.
Since no division or multiplication of a negative number occurred, the inequality sign remains the same.
Example Question #2231 : Algebra 1
Simplify the following inequality:
To do this question all you need to do is divide both sides by
So,
Which gives you:
It is important to remember that the greater than sign flips to less than when dividing by a negative number.
Example Question #22 : How To Find The Solution To An Inequality With Division
Solve the following inequality for :
First, using the additive inverses, isolate the variables and constants on either side of the equation. In other words, subtract from both sides, and subtract from both sides. This leaves you with:
Now use the multiplicative inverse (divide by ) to solve the inequality.
Keep in mind that we do not flip the inequality symbol because the number we were dividing by is positive.
Example Question #104 : Equations / Inequalities
Find all of the solutions to this inequality.
To solve an inequality, isolate the variable on one side with all other constants on the other side. To accomplish this, perform opposite operations to manipulate the inequality.
First, isolate the x by multiplying each side by four.
Whatever you do to one side you must also do to the other side.
This gives you:
The answer, therefore, is .
Example Question #105 : Equations / Inequalities
Solve the following inequality:
To isolate the variable, first subtract four on both sides.
Simplify the left and the right side of the equation.
Divide by negative two on both sides. When dividing by a negative number, be sure to switch the sign.
The answer is:
Example Question #2232 : Algebra 1
Solve:
Divide by negative two on both sides. When dividing a negative number, switch the sign of the inequality.
Simplify both sides of the equation.
The answer is:
Example Question #2233 : Algebra 1
Solve the inequaltiy:
Divide both sides by negative nine. When we divide by a negative sign, be sure to switch the sign.
Simplify both sides.
The answer is:
