Weegy: You want to separate the variables from the non variables. You can either subtract 7x or 12x. If you subtract 7x, then it'll be 5x and your non variable side will be -20. If you subtract 12x then it'll be -5x, then the non variable side will be 20. [ The diagrams below will help you understand
Subtracting 7x:
7x-7=13+12x
-7=13+12x-7x
Bring 13 on other side of equation
-20=5x
x=-4
Subtracting 12x:
7x-7=13+12x
7x-12x-7=13
Bring -7 on other side of equation
-5x=20
x=-4 ]
User: 7x-7=12x+13 The solution is x=?
Weegy: x = -4
User: simplify 7(-2y^5)
