Question

Plz help 7b+3=24
Thank you

Answer 1

3

Explanation:

We do do -3 on both sides and get 7b = 21. Then we multiply by the reciprocal (divide) (7b * 1/7 = 21 * 1/7) . We get b = 21/7 cause the 7's cancel out. b = 3 cause 21/7 = 3

Answer 2

Simplifying
7b + 3 = 24

Reorder the terms:
3 + 7b = 24

Solving
3 + 7b = 24

Solving for variable 'b'.

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

Add '-3' to each side of the equation.
3 + -3 + 7b = 24 + -3

Combine like terms: 3 + -3 = 0
0 + 7b = 24 + -3
7b = 24 + -3

Combine like terms: 24 + -3 = 21
7b = 21

Divide each side by '7'.
b = 3

Simplifying
b = 3
