Solve l_{1}:y=5x.quadl_{2}:y=-5x

$$l _ { 1 } : y = 5 x . \quad l _ { 2 } : y = - 5 x$$

Solve for x

$$x=\frac{l_{1}}{5y}$$

$$y\neq 0$$

Steps for Solving Linear Equation

Multiply both sides of the equation by y.

$$l_{1}=5xy$$

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

$$5xy=l_{1}$$

The equation is in standard form.

$$5yx=l_{1}$$

Divide both sides by 5y.

$$\frac{5yx}{5y}=\frac{l_{1}}{5y}$$

Dividing by 5y undoes the multiplication by 5y.

$$x=\frac{l_{1}}{5y}$$

Solve for l_1

$$l_{1}=5xy$$

$$y\neq 0$$

Solution Steps

Multiply both sides of the equation by y.

$$l_{1}=5xy$$
