7+5(x-2) = 3(5x+1)-12 solve for
x
1. First we would have to multiply the numbers in the
parentheses by the number that is outside of it. 7 + 5x - 10 = 15x + 3 -
12
2. Then, add all like terms. 5x - 3 = 15x -
9
3. Now, we want all of the x's to one side and
the integers to the other side. So we subtract 5x from both sides and add 9 to both
sides. 6 = 10x
4. Finally, we divide 10 from both sides
to get the x alone. 6/10 = x
5. Simplify 3/5 =
x
6. Now we know that x = 3/5 or
.60
