How to solve x + 2x = 3x + 4x

1. Factor the equation (x + 2)(x + 3) = 0. 2. Set each factor equal to zero: x + 2 = 0 and x + 3 = 0. 3. Solve for x: x = -2 and x = -3.

Question

$$x+2x=3x+4x$$

Solve for x

$x=0$

Steps for Solving Linear Equation

Combine $x$ and $2x$ to get $3x$.

$$3x=3x+4x$$

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

$$3x=7x$$

Subtract $7x$ from both sides.

$$3x-7x=0$$

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

$$-4x=0$$

Product of two numbers is equal to $0$ if at least one of them is $0$. Since $-4$ is not equal to $0$, $x$ must be equal to $0$.

$$x=0$$
