How to solve (x+1)+(x-3)=15

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

$$(x+1)+(x-3)=15$$

Solve for x

$x = \frac{17}{2} = 8\frac{1}{2} = 8.5$

Steps for Solving Linear Equation

Combine $x$ and $x$ to get $2x$.

$$2x+1-3=15$$

Subtract $3$ from $1$ to get $-2$.

$$2x-2=15$$

Add $2$ to both sides.

$$2x=15+2$$

Add $15$ and $2$ to get $17$.

$$2x=17$$

Divide both sides by $2$.

$$x=\frac{17}{2}$$
