How to solve 2x-y+1=0

1. Factor the equation (x + 2)(x + 3) = 0. 2. Set each factor equal to zero: x + 2 = 0 and x + 3 = 0. 3. Solve for x: x = -2 and x = -3.

Question

$$2x-y+1=0$$

Solve for x

$x=\frac{y-1}{2}$

Steps for Solving Linear Equation

Add $y$ to both sides. Anything plus zero gives itself.

$$2x+1=y$$

Subtract $1$ from both sides.

$$2x=y-1$$

Divide both sides by $2$.

$$\frac{2x}{2}=\frac{y-1}{2}$$

Dividing by $2$ undoes the multiplication by $2$.

$$x=\frac{y-1}{2}$$

Show Solution

Solve for y

$y=2x+1$

Steps for Solving Linear Equation

Subtract $2x$ from both sides. Anything subtracted from zero gives its negation.

$$-y+1=-2x$$

Subtract $1$ from both sides.

$$-y=-2x-1$$

Divide both sides by $-1$.

$$\frac{-y}{-1}=\frac{-2x-1}{-1}$$

Dividing by $-1$ undoes the multiplication by $-1$.

$$y=\frac{-2x-1}{-1}$$

Divide $-2x-1$ by $-1$.

$$y=2x+1$$
