Question

$$\frac{-5x}{42}=\frac{4x}{21}$$

Solve for x

$x=0$

Steps for Solving Linear Equation

Multiply both sides of the equation by $42$, the least common multiple of $42,21$.

$$-5x=2\times 4x$$

Multiply $2$ and $4$ to get $8$.

$$-5x=8x$$

Subtract $8x$ from both sides.

$$-5x-8x=0$$

Combine $-5x$ and $-8x$ to get $-13x$.

$$-13x=0$$

Product of two numbers is equal to $0$ if at least one of them is $0$. Since $-13$ is not equal to $0$, $x$ must be equal to $0$.

$$x=0$$
