Answer: 6 = - 2.
Step by step explanation:
Subtract 4b from 7b.
3b + 3 = 3 - 3 (b+4)
Simplify 3 - 3 (b+4).
3b + 3 = - 3b - 9
Move all terms containing b to the left side of the equation.
6b + 3 = - 9.
Move all terms not containing b to the right of the equation.
6b = - 12
Divide each term by 6 and simplify.
And, voila! You have your answer, 6 = - 2.
