Example Question #565 : Algebraic Concepts
Solve for b when f is equal to 0
No real solutions
No real solutions
Solve for b when f is equal to 0
Let's start by plugging in 0 for f
Now, we cannot go any further, because we cannot divide by zero.
This means that there is no value of b for which f will equal zero.
This means we have no real solutions.
Example Question #362 : Equations
Solve the following equation for u when y is equal to 6.
Solve the following equation for u when y is equal to 6.
To begin, let's plug in 6 for y.
Next, bring the u over to the other side by multiplying both sides by u
Finally, divide both sides by 12 to see what u is
So we get u=2 as our answer.
Example Question #2682 : Isee Middle Level (Grades 7 8) Mathematics Achievement
Solve for x in the following equation:
To solve for x, we want x to stand alone or to be by itself. So in the equation
we want x to stand alone. To do that, we need to cancel the that is next to it. The is being multiplied to x, so to cancel it out, we will need to divide by . If we divide by on the left side of the equal sign, we have to divide by on the right side of the equal sign. So,
Now, we simplify.
Example Question #364 : Equations
Evaluate .
To evaluate, substitute -40 in for A.
Add 40 to each side to isolate and solve for B.
Example Question #365 : Equations
Solve the equation:
To solve the equation, isolate the variable on one side of the equation and all other constants on the other side. To accomplish this, perform the opposite operation to manipulate the equation.
First add seven to both sides.
Now divide by five on both sides.
Example Question #366 : Equations
Solve the following equation for y when
Solve the following equation for y when
Let's begin by rearranging the equation to get y by itself.
Next, just plug in 3 for z and solve.
So our answer is
Example Question #367 : Equations
Solve for :
To divide, move the decimal point in both numbers two units to the right;
Example Question #368 : Equations
Solve the following equation for h, when l is equal to 5
Solve the following equation for h, when l is equal to 5
Let's begin by substituting in 5 for l
Simplify
Next, move the twelve over:
Finally, we get:
Example Question #2691 : Isee Middle Level (Grades 7 8) Mathematics Achievement
Solve for the equation when ,
.
The first step is to plug in your value so your equation looks like,
.
Then you multiply to get .
Then you add to get your final answer .
Example Question #2692 : Isee Middle Level (Grades 7 8) Mathematics Achievement
Solve for x in the following:
To solve for x, we want x to stand alone or be by itself. So,
we want to get x to be by itself. To do that, we need to move the . To move it, we need to cancel it out. To cancel it out, we must (add 8). If we add 8 on the left side of the equal sign, we must add 8 on the right side of the equal sign. So,
