Question

$$9 \times [ ( - 7 ) + 3 ] = ( 9 ) \times x + ( 9 ) \times 3$$

Solve for x

$x=-7$

Steps for Solving Linear Equation

Add $-7$ and $3$ to get $-4$.

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

Multiply $9$ and $-4$ to get $-36$.

$$-36=9x+9\times 3$$

Multiply $9$ and $3$ to get $27$.

$$-36=9x+27$$

Swap sides so that all variable terms are on the left hand side.

$$9x+27=-36$$

Subtract $27$ from both sides.

$$9x=-36-27$$

Subtract $27$ from $-36$ to get $-63$.

$$9x=-63$$

Divide both sides by $9$.

$$x=\frac{-63}{9}$$

Divide $-63$ by $9$ to get $-7$.

$$x=-7$$
