Example Question #563 : Algebra 1
Solve for :
The equation has no solution.
Example Question #31 : How To Solve Two Step Equations
Solve for .
Notice that can be canceled out by subtracting it from both sides.
Now, we can isolate . First, we need to get all the variables on the same side by adding to each side.
Subtract from both sides.
Finally, multiply both sides by .
Example Question #32 : How To Solve Two Step Equations
Solve for :
The equation has no solution.
The equation has no solution.
This statement is identically false, so the original equation has no solution.
Example Question #565 : Linear Equations
Solve for :
Example Question #566 : Linear Equations
Solve for :
Example Question #32 : How To Solve Two Step Equations
Solve for :
Example Question #567 : Linear Equations
Solve for :
The solution set is the set of all real numbers.
The solution set is the set of all real numbers.
This statement is identically true; therefore, the solution set is the set of all real numbers.
Example Question #33 : How To Solve Two Step Equations
Call the three angles of a triangle . The measure of is twenty degrees more than that of ; the measure of is forty degrees less than twice that of . What is the greatest measure of any of the three angles of the triangle?
Call the measure of . Since the measure of is twenty degrees more than that of , we can say that has measure . Since the measure of is forty degrees less than twice that of , we can say that has measure .
The sum of the measures of the three angles of a triangle is 180, so we can set up and solve an equation that sets the sum of these three expressions equal to 180:
Substitute 50 for in the other two expressions:
The triangle has angles measuring , so the answer to the question is .
Example Question #34 : How To Solve Two Step Equations
Solve for :
Example Question #572 : Linear Equations
Find the value of in the following linear equation and select the correct answer from the choices listed below.
Solve equation by using inverse order of operations to get by itself.
Order of operations: PEMDAS. Addition and subtraction usually come last, so when using inverse order of operations to "undo an expression," they come first. 8 is being added to , so subtract 8 from both sides in order to get alone.
Next comes multiplication/division. is being multiplied by 2, so divide both sides by 2 to get on its own.
