Question

Solve the equation. 7b - 3 = -2b + 24

Answer 1

Equation: $7b-3=-2b+24$

When solving these type of equations, you have to get the variable on one side by "itself".

To start off, add 2b to both sides

$7b+2b-3=-2b+2b+24$

Now add 3 to both sides

$9b-3+3=24+3$

It is now $9b=27$

Now divide 27 by 9 (don't worry about the variable because you're dividing to FIND the variable value)

$27$ ÷ $9=3$

Answer: $b=3$

Answer 2

7b - 3 = -2b + 24
7b + 2b = 24 + 3
9b = 27
b = 27/9
b =3
