Question

3(x-4)<-15 solve for x

Answer 1

3(x - 4) < -15

Divide Each side by 3:

Add 5 to both sides:

x < -1

Hope this helps!

Answer 2

you can do anything to an equaiton as long as you do it to both sides
if you multiply or divide both sides by a negative, flip the inequality direction

3(x-4)<-15
divide both sides by 3
x-4<-5
add 4 to both sides
x<-1
