Solve y=-2/5x+3

$$y = \frac { - 2 } { 5 } x + 3$$

Solve for x

$$x=\frac{15-5y}{2}$$

Steps for Solving Linear Equation

Fraction \frac{-2}{5} can be rewritten as -\frac{2}{5} by extracting the negative sign.

$$y=-\frac{2}{5}x+3$$

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

$$-\frac{2}{5}x+3=y$$

Subtract 3 from both sides.

$$-\frac{2}{5}x=y-3$$

Divide both sides of the equation by -\frac{2}{5}, which is the same as multiplying both sides by the reciprocal of the fraction.

$$\frac{-\frac{2}{5}x}{-\frac{2}{5}}=\frac{y-3}{-\frac{2}{5}}$$

Dividing by -\frac{2}{5} undoes the multiplication by -\frac{2}{5}.

$$x=\frac{y-3}{-\frac{2}{5}}$$

Divide y-3 by -\frac{2}{5} by multiplying y-3 by the reciprocal of -\frac{2}{5}.

$$x=\frac{15-5y}{2}$$

Solve for y

$$y=-\frac{2x}{5}+3$$
