How to solve E = 5/4 - 7/12 F

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.

$$E = \frac { 5 } { 4 } - \frac { 7 } { 12 }$$

$E=\frac{2}{3}\approx 0.666666667$

Least common multiple of $4$ and $12$ is $12$. Convert $\frac{5}{4}$ and $\frac{7}{12}$ to fractions with denominator $12$.

$$E=\frac{15}{12}-\frac{7}{12}$$

Since $\frac{15}{12}$ and $\frac{7}{12}$ have the same denominator, subtract them by subtracting their numerators.

$$E=\frac{15-7}{12}$$

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

$$E=\frac{8}{12}$$

Reduce the fraction $\frac{8}{12}$ to lowest terms by extracting and canceling out $4$.

$$E=\frac{2}{3}$$

$E≔\frac{2}{3}$
