Question

13(3x-1)-2(8+6x)=52 x=? Can you solve this for me, because I don't understand how to do it.

Answer 1

First, open the brackets by multiplying its contents with its coefficient. From there, everything is pretty straight forward.
(39x-13)-(16+12x)=52
Therefore, 39x-13-16-12x=52
39x-12x-13-16=52
Thus 27x-13-16=52
27x=52+13+16
27x=81
x=81/27. x=3
