Question

$$x\times[7+(-8)]=15\times7+(-8)\times15$$

Solve for x

$x=15$

Steps for Solving Linear Equation

Subtract $8$ from $7$ to get $-1$.

$$x\left(-1\right)=15\times 7-8\times 15$$

Multiply $15$ and $7$ to get $105$. Multiply $-8$ and $15$ to get $-120$.

$$x\left(-1\right)=105-120$$

Subtract $120$ from $105$ to get $-15$.

$$x\left(-1\right)=-15$$

Multiply both sides by $-1$.

$$x=15$$
