Question

$$(3-7x)/(15+2x)=0$$

Solve for x

$x=\frac{3}{7}\approx 0.428571429$

Steps for Solving Linear Equation

Variable $x$ cannot be equal to $-\frac{15}{2}$ since division by zero is not defined. Multiply both sides of the equation by $2x+15$.

$$3-7x=0$$

Subtract $3$ from both sides. Anything subtracted from zero gives its negation.

$$-7x=-3$$

Divide both sides by $-7$.

$$x=\frac{-3}{-7}$$

Fraction $\frac{-3}{-7}$ can be simplified to $\frac{3}{7}$ by removing the negative sign from both the numerator and the denominator.

$$x=\frac{3}{7}$$
