Solve 0.05x+0.07y=2020

$$0.05 x + 0.07 y = 2020$$

Solve for x

$$x=-\frac{7y}{5}+40400$$

Steps for Solving Linear Equation

Subtract 0.07y from both sides.

$$0.05x=2020-0.07y$$

The equation is in standard form.

$$0.05x=-\frac{7y}{100}+2020$$

Multiply both sides by 20.

$$\frac{0.05x}{0.05}=\frac{-\frac{7y}{100}+2020}{0.05}$$

Dividing by 0.05 undoes the multiplication by 0.05.

$$x=\frac{-\frac{7y}{100}+2020}{0.05}$$

Divide 2020-\frac{7y}{100} by 0.05 by multiplying 2020-\frac{7y}{100} by the reciprocal of 0.05.

$$x=-\frac{7y}{5}+40400$$

Solve for y

$$y=\frac{202000-5x}{7}$$

Steps for Solving Linear Equation

Subtract 0.05x from both sides.

$$0.07y=2020-0.05x$$

The equation is in standard form.

$$0.07y=-\frac{x}{20}+2020$$

Divide both sides of the equation by 0.07, which is the same as multiplying both sides by the reciprocal of the fraction.

$$\frac{0.07y}{0.07}=\frac{-\frac{x}{20}+2020}{0.07}$$

Dividing by 0.07 undoes the multiplication by 0.07.

$$y=\frac{-\frac{x}{20}+2020}{0.07}$$

Divide 2020-\frac{x}{20} by 0.07 by multiplying 2020-\frac{x}{20} by the reciprocal of 0.07.

$$y=\frac{202000-5x}{7}$$
