-3/4 B=21 solve for B

B= −252


B = −28


B = 28


B= 252

Answer 1

The answer is B) B = -28.

Here are the steps I did.

1. Simplify 3/4B to 3B/4 ( -3B/4 = 21 )

2. Multiply both sides by 4 ( -3B = 21 * 4 )

3. Simplify 21 * 4 to 84 ( -3B = 84 )

4. Divide both sides by -3 ( B = -84/3 )

5. Simplify 84/3 to 28 ( B = -28 )

Answer 2

Your answer would be B=-28
