Question

Solve for q. 6q = -8 + 7q

Answer 1

`q = 8`

Explanation:

`6q = -8 + 7q \\ 7q -8 = 6q \\ 7q - 6q - 8 = 0 \\ q = 8`

Answer 2

6q = -8 + 7q

move 7q to the other side

sign changes from +7q to -7q

6q-7q= -8+7q-7q (combine like terms)

6q-7q= -8

-q= -8

mutiply both sides by -1 to get +q

(-q)(-1)= (-8)(-1)

Answer:

q= 8
