Question

$$2x-4x=7$$

Solve for x

$x = -\frac{7}{2} = -3\frac{1}{2} = -3.5$

Steps for Solving Linear Equation

Combine $2x$ and $-4x$ to get $-2x$.

$$-2x=7$$

Divide both sides by $-2$.

$$x=\frac{7}{-2}$$

Fraction $\frac{7}{-2}$ can be rewritten as $-\frac{7}{2}$ by extracting the negative sign.

$$x=-\frac{7}{2}$$
