Question

$$7M-5=2M+8$$

Solve for M

$M = \frac{13}{5} = 2\frac{3}{5} = 2.6$

Steps for Solving Linear Equation

Subtract $2M$ from both sides.

$$7M-5-2M=8$$

Combine $7M$ and $-2M$ to get $5M$.

$$5M-5=8$$

Add $5$ to both sides.

$$5M=8+5$$

Add $8$ and $5$ to get $13$.

$$5M=13$$

Divide both sides by $5$.

$$M=\frac{13}{5}$$
