Solve y=(xdiv20)+(xdiv30)

$$y=(x \div 20)+(x \div 30)$$

Solve for x

$$x=12y$$

Steps for Solving Linear Equation

Combine \frac{x}{20} and \frac{x}{30} to get \frac{1}{12}x.

$$y=\frac{1}{12}x$$

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

$$\frac{1}{12}x=y$$

Multiply both sides by 12.

$$\frac{\frac{1}{12}x}{\frac{1}{12}}=\frac{y}{\frac{1}{12}}$$

Dividing by \frac{1}{12} undoes the multiplication by \frac{1}{12}.

$$x=\frac{y}{\frac{1}{12}}$$

Divide y by \frac{1}{12} by multiplying y by the reciprocal of \frac{1}{12}.

$$x=12y$$

Solve for y

$$y=\frac{x}{12}$$

Solution Steps

Combine \frac{x}{20} and \frac{x}{30} to get \frac{1}{12}x.

$$y=\frac{1}{12}x$$
