Question

$$\frac{2x-7x}{3}=\frac{1+3}{15}$$

Solve for x

$x=-\frac{4}{25}=-0.16$

Steps for Solving Linear Equation

Multiply both sides of the equation by $15$, the least common multiple of $3,15$.

$$5\left(2x-7x\right)=1+3$$

Combine $2x$ and $-7x$ to get $-5x$.

$$5\left(-5\right)x=1+3$$

Multiply $5$ and $-5$ to get $-25$.

$$-25x=1+3$$

Add $1$ and $3$ to get $4$.

$$-25x=4$$

Divide both sides by $-25$.

$$x=\frac{4}{-25}$$

Fraction $\frac{4}{-25}$ can be rewritten as $-\frac{4}{25}$ by extracting the negative sign.

$$x=-\frac{4}{25}$$
