Question

$$7b-15=5b-3......b=$$

Solve for b

$b=6$

Steps for Solving Linear Equation

Subtract $5b$ from both sides.

$$7b-15-5b=-3$$

Combine $7b$ and $-5b$ to get $2b$.

$$2b-15=-3$$

Add $15$ to both sides.

$$2b=-3+15$$

Add $-3$ and $15$ to get $12$.

$$2b=12$$

Divide both sides by $2$.

$$b=\frac{12}{2}$$

Divide $12$ by $2$ to get $6$.

$$b=6$$
