Question

b-9+6b=30
plz help me

Answer 1

Simplifying
b + -9 + -6b = 30

Reorder the terms:
-9 + b + -6b = 30

Combine like terms: b + -6b = -5b
-9 + -5b = 30

Solving
-9 + -5b = 30

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 + -5b = 30 + 9

Combine like terms: -9 + 9 = 0
0 + -5b = 30 + 9
-5b = 30 + 9

Combine like terms: 30 + 9 = 39
-5b = 39

Divide each side by '-5'.
b = -7.8

Simplifying
b = -7.8
