Solve 2m-3=-M

$$2 m - 3 = - M$$

Solve for M

$$M=3-2m$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$-M=2m-3$$

Divide both sides by -1.

$$\frac{-M}{-1}=\frac{2m-3}{-1}$$

Dividing by -1 undoes the multiplication by -1.

$$M=\frac{2m-3}{-1}$$

Divide 2m-3 by -1.

$$M=3-2m$$

Solve for m

$$m=\frac{3-M}{2}$$

Steps for Solving Linear Equation

Add 3 to both sides.

$$2m=-M+3$$

The equation is in standard form.

$$2m=3-M$$

Divide both sides by 2.

$$\frac{2m}{2}=\frac{3-M}{2}$$

Dividing by 2 undoes the multiplication by 2.

$$m=\frac{3-M}{2}$$
