7b+3-4b=3-3(b+4) solve and give work .

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.
