-6u + 7 = -29
-6u + 7 - 7 = -29 - 7
-6u = -36
-6u / -6 = -36 / -6
u = 6

you want to solve for u, what you would do is to put all the integers on the other side of the equation.
-6u + 7 = -29 --> subtract 7 from both sides so that -6u will be the only one on the left.
-6u = -29 - 7 ---> combine like terms and divide both sides by -6 to get u.
-6u = -36
u = 6

u=6
-29-7 = -36
so
-6u=-36
u=6

The idea is to have the u by itself. You remove whatever is farther. So, you subtract seven from each side. Whatever you do to one side you do to another. The seven on the right side is zero. Then it is negative twenty-nine plus negative seven. That will be negative thirty-six. You divide negative six to both sides. You have to do the opposite so,it will be canceled. That will give you u equals six because a negative divided by a negative is a positive. =6

-6u=-36
-6u/-6=-36/-6
u=6
