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

Answer:
3
Step-by-step 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
