Solve -5/2+21/2+m+2=0

$$\frac { - 5 } { 2 } + \frac { 21 } { 2 } + m + 2 = 0$$

Solve for m

$$m=-10$$

Steps for Solving Linear Equation

Fraction \frac{-5}{2} can be rewritten as -\frac{5}{2} by extracting the negative sign.

$$-\frac{5}{2}+\frac{21}{2}+m+2=0$$

Since -\frac{5}{2} and \frac{21}{2} have the same denominator, add them by adding their numerators.

$$\frac{-5+21}{2}+m+2=0$$

Add -5 and 21 to get 16.

$$\frac{16}{2}+m+2=0$$

Divide 16 by 2 to get 8.

$$8+m+2=0$$

Add 8 and 2 to get 10.

$$10+m=0$$

Subtract 10 from both sides. Anything subtracted from zero gives its negation.

$$m=-10$$
