How to solve (1)/(2)(-1)-(-4)

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.

Question

$$\frac{ 1 }{ 2 } (-1)-(-4)$$

Evaluate

$\frac{7}{2}=3.5$

Solution Steps

Multiply $\frac{1}{2}$ and $-1$ to get $-\frac{1}{2}$.

$$-\frac{1}{2}-\left(-4\right)$$

The opposite of $-4$ is $4$.

$$-\frac{1}{2}+4$$

Convert $4$ to fraction $\frac{8}{2}$.

$$-\frac{1}{2}+\frac{8}{2}$$

Since $-\frac{1}{2}$ and $\frac{8}{2}$ have the same denominator, add them by adding their numerators.

$$\frac{-1+8}{2}$$

Add $-1$ and $8$ to get $7$.

$$\frac{7}{2}$$
