Question

$$(3x+4x)=12x$$

Solve for x

$x=0$

Steps for Solving Linear Equation

Combine $3x$ and $4x$ to get $7x$.

$$7x=12x$$

Subtract $12x$ from both sides.

$$7x-12x=0$$

Combine $7x$ and $-12x$ to get $-5x$.

$$-5x=0$$

Product of two numbers is equal to $0$ if at least one of them is $0$. Since $-5$ is not equal to $0$, $x$ must be equal to $0$.

$$x=0$$
