Question

$$7 - 2 ( x + 1 ) = 3 x + 8$$

Solve for x

$x=-\frac{3}{5}=-0.6$

Steps for Solving Linear Equation

Use the distributive property to multiply $-2$ by $x+1$.

$$7-2x-2=3x+8$$

Subtract $2$ from $7$ to get $5$.

$$5-2x=3x+8$$

Subtract $3x$ from both sides.

$$5-2x-3x=8$$

Combine $-2x$ and $-3x$ to get $-5x$.

$$5-5x=8$$

Subtract $5$ from both sides.

$$-5x=8-5$$

Subtract $5$ from $8$ to get $3$.

$$-5x=3$$

Divide both sides by $-5$.

$$x=\frac{3}{-5}$$

Fraction $\frac{3}{-5}$ can be rewritten as $-\frac{3}{5}$ by extracting the negative sign.

$$x=-\frac{3}{5}$$
