Solve 0.9x+0.8y=825

$$0.9 x + 0.8 y = 825$$

Solve for x

$$x=-\frac{8y}{9}+\frac{2750}{3}$$

Steps for Solving Linear Equation

Subtract 0.8y from both sides.

$$0.9x=825-0.8y$$

The equation is in standard form.

$$0.9x=-\frac{4y}{5}+825$$

Divide both sides of the equation by 0.9, which is the same as multiplying both sides by the reciprocal of the fraction.

$$\frac{0.9x}{0.9}=\frac{-\frac{4y}{5}+825}{0.9}$$

Dividing by 0.9 undoes the multiplication by 0.9.

$$x=\frac{-\frac{4y}{5}+825}{0.9}$$

Divide 825-\frac{4y}{5} by 0.9 by multiplying 825-\frac{4y}{5} by the reciprocal of 0.9.

$$x=-\frac{8y}{9}+\frac{2750}{3}$$

Solve for y

$$y=-\frac{9x}{8}+1031.25$$

Steps for Solving Linear Equation

Subtract 0.9x from both sides.

$$0.8y=825-0.9x$$

The equation is in standard form.

$$0.8y=-\frac{9x}{10}+825$$

Divide both sides of the equation by 0.8, which is the same as multiplying both sides by the reciprocal of the fraction.

$$\frac{0.8y}{0.8}=\frac{-\frac{9x}{10}+825}{0.8}$$

Dividing by 0.8 undoes the multiplication by 0.8.

$$y=\frac{-\frac{9x}{10}+825}{0.8}$$

Divide 825-\frac{9x}{10} by 0.8 by multiplying 825-\frac{9x}{10} by the reciprocal of 0.8.

$$y=-\frac{9x}{8}+\frac{4125}{4}$$
