Question

$$x + \frac { 3 } { 4 } = \frac { 2 } { 5 }$$

Solve for x

$x=-\frac{7}{20}=-0.35$

Steps for Solving Linear Equation

Subtract $\frac{3}{4}$ from both sides.

$$x=\frac{2}{5}-\frac{3}{4}$$

Least common multiple of $5$ and $4$ is $20$. Convert $\frac{2}{5}$ and $\frac{3}{4}$ to fractions with denominator $20$.

$$x=\frac{8}{20}-\frac{15}{20}$$

Since $\frac{8}{20}$ and $\frac{15}{20}$ have the same denominator, subtract them by subtracting their numerators.

$$x=\frac{8-15}{20}$$

Subtract $15$ from $8$ to get $-7$.

$$x=-\frac{7}{20}$$
