Solve 300-1.05*x=y

$$300-1.05 \times x=y$$

Solve for x

$$x=-\frac{20y}{21}+\frac{2000}{7}$$

Steps for Solving Linear Equation

Subtract 300 from both sides.

$$-1.05x=y-300$$

Divide both sides of the equation by -1.05, which is the same as multiplying both sides by the reciprocal of the fraction.

$$\frac{-1.05x}{-1.05}=\frac{y-300}{-1.05}$$

Dividing by -1.05 undoes the multiplication by -1.05.

$$x=\frac{y-300}{-1.05}$$

Divide y-300 by -1.05 by multiplying y-300 by the reciprocal of -1.05.

$$x=-\frac{20y}{21}+\frac{2000}{7}$$

Solve for y

$$y=-\frac{21x}{20}+300$$

Solution Steps

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

$$y=300-1.05x$$
