Question

what is the solution to this equation?
7-9b=-8b+8

Answer 1

minus 7 from each side of the equation.

7-7-9b=-8b+8-7
So -9b=-8b+1

Answer 2

Multiply by -1 to get:

9b=8b-1

Answer 3

Sure you can work the rest out. gl

Answer 4

Slightly different approach:

Add 9b to each side of the equation to get
\[7-9b+9b= -8b + 9b + 8\]\[7 = b+ 8\]\[b = 7 - 8 = -1\]

As long as you do the same thing to both sides of the equation, you're good.
