Solve Using the Quadratic Formula 3m+8=15

$3 m + 8 = 15$

Move all terms to the left side of the equation and simplify.

Subtract $15$ from both sides of the equation.

$3 m + 8 - 15 = 0$

Subtract $15$ from $8$ .

$3 m - 7 = 0$

Add $7$ to both sides of the equation.

$3 m = 7$

Divide each term in $3 m = 7$ by $3$ and simplify.

Divide each term in $3 m = 7$ by $3$ .

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

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

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

Divide $m$ by $1$ .

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