One Step Equations with Adding Subtracting Multiplication and Division

$$3x=12$$ , where "x" is the number of boxes.

$$3x=12$$ , where "x" is the cost of one box of envelopes.

$$12x=3$$ , where "x" is the number of boxes.

$$12x=3$$ , where "x" is the cost of one box of envelopes.

Multiply both sides of the equation by 26.

Multiply both sides of the equation by 13.

Divide both sides of the equation by 13.

Divide both sides of the equation by 26.

$$\frac{1}{2}\left(24.28\right)=m$$

$$m\div2=24.28$$

$$m\times2=24.28$$

$$\frac{24.28}{2}=m$$
