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.
\frac{-15x}{-15}=\frac{-12}{-15}
x=\frac{4}{5}

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