How to solve 7x+15 < x+3

Q: How to solve 7x+15 < x+3

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

$$7x+15 < x+3$$

Solve for x

$x<-2$

Solution Steps

Subtract $x$ from both sides.

$$7x+15-x<3$$

Combine $7x$ and $-x$ to get $6x$.

$$6x+15<3$$

Subtract $15$ from both sides.

$$6x<3-15$$

Subtract $15$ from $3$ to get $-12$.

$$6x<-12$$

Divide both sides by $6$. Since $6$ is positive, the inequality direction remains the same.

$$x<\frac{-12}{6}$$

Divide $-12$ by $6$ to get $-2$.

$$x<-2$$
