y=2x-5 for x

Question

Solve each of the following equations for the indicated variables. Show all of your steps. 

Answer 1

y=2x-5

 

It indicates to solve for x. So we want to get x by itself, not y. 

 

So you want to move everything but the x to the other side.

 

Add 5 to both sides.

 

y+5=2x

 

Then divide both sides by two.

 

y/2 + 5/2=x

 

Simple as that :)
