Question

$$(35-x)\cdot7-42=56$$

Solve for x

$x=21$

Steps for Solving Linear Equation

Use the distributive property to multiply $35-x$ by $7$.

$$245-7x-42=56$$

Subtract $42$ from $245$ to get $203$.

$$203-7x=56$$

Subtract $203$ from both sides.

$$-7x=56-203$$

Subtract $203$ from $56$ to get $-147$.

$$-7x=-147$$

Divide both sides by $-7$.

$$x=\frac{-147}{-7}$$

Divide $-147$ by $-7$ to get $21$.

$$x=21$$
