Question

$$12 - ( 5 x - 9 ) = 4 x + 3$$

Solve for x

$x=2$

Steps for Solving Linear Equation

To find the opposite of $5x-9$, find the opposite of each term.

$$12-5x-\left(-9\right)=4x+3$$

The opposite of $-9$ is $9$.

$$12-5x+9=4x+3$$

Add $12$ and $9$ to get $21$.

$$21-5x=4x+3$$

Subtract $4x$ from both sides.

$$21-5x-4x=3$$

Combine $-5x$ and $-4x$ to get $-9x$.

$$21-9x=3$$

Subtract $21$ from both sides.

$$-9x=3-21$$

Subtract $21$ from $3$ to get $-18$.

$$-9x=-18$$

Divide both sides by $-9$.

$$x=\frac{-18}{-9}$$

Divide $-18$ by $-9$ to get $2$.

$$x=2$$
