Question

?? what is the solution? ? -2(x+4)+7x<-18

Answer 1

`-2(x+4)+7x < -18\ \ \ \ |\text{use distributive property}\\\\(-2)(x)+(-2)(4)+7x < -18\\\\-2x-8+7x < -18\\\\-2x+7x-8 < -18\ \ \ \ |\text{add 8 to both sides}\\\\(-2x+7x) < -10\\\\5x < -10\ \ \ \ |\text{divide both sides by 5}\\\\x < -5\to x\in(-\infty,\ 5)`
