If 12-5×=-13, what would x be?

12-5x=-13 

Step one: subtract 12 from each side of the equal sign... Therefore, -5x=-13-12. Simplify.

-5x=-25

Step two: get x by itself. So divide by -5 on both side of the equal sign... 

x=5

If 12-5×=-13, what would x be?

Move x to one side and the other numbers to the other,

So, -5x=-13-12=-25

-x=-25/-5 or

x=5
