Solve {l}{0.8x-0.3y=800}{text{esolutionis}}

$$\left. \begin{array} { l } { 0.8 x - 0.3 y = 800 } \\ { \text { e solution is } } \end{array} \right.$$

Solve for x

$$x=\frac{3y}{8}+1000$$

Steps for Solving Linear Equation

Add 0.3y to both sides.

$$0.8x=800+0.3y$$

The equation is in standard form.

$$0.8x=\frac{3y}{10}+800$$

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

$$\frac{0.8x}{0.8}=\frac{\frac{3y}{10}+800}{0.8}$$

Dividing by 0.8 undoes the multiplication by 0.8.

$$x=\frac{\frac{3y}{10}+800}{0.8}$$

Divide 800+\frac{3y}{10} by 0.8 by multiplying 800+\frac{3y}{10} by the reciprocal of 0.8.

$$x=\frac{3y}{8}+1000$$
