How to solve a y = 2x - 1

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

$$y = 2 x - 1$$

Solve for x

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

Steps for Solving Linear Equation

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

$$2x-1=y$$

Add $1$ to both sides.

$$2x=y+1$$

Divide both sides by $2$.

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

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

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