Question

Simplify 9 - 8b + 6b

Answer 1

Simplifying
9 + -8b + 6b = 0

Combine like terms: -8b + 6b = -2b
9 + -2b = 0

Solving
9 + -2b = 0

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Add '-9' to each side of the equation.
9 + -9 + -2b = 0 + -9

Combine like terms: 9 + -9 = 0
0 + -2b = 0 + -9
-2b = 0 + -9

Combine like terms: 0 + -9 = -9
-2b = -9

Divide each side by '-2'.
b = 4.5

Simplifying
b = 4.5
