-2x+7=13x-5
13x + 2x = 7 + 5
15x = 12
x = 12/15
x = 4/5

Hey!

Let's start writing this problem.

-2x+7=13x-5
Subtract
7 from both sides.

-2x+7-7=13x-5-7

-2x=13x-12
Subtract
13x from both sides.

-2x-13x=13x-12-13x

-15x=-12
Divide both sides by
-15.

(-15x)/(-15)=(-12)/(-15)

x=(4)/(5)

Let me know if you have any questions regarding this problem!
Thanks!
