Hello there!
Answer:
Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
First, you expand.
4(x-2)=4x-8
7x+1<4x-8
Subtract by 1 both sides of an equation.
7x+1-1<4x-8-1
Add/Subtract numbers from left/right.
8+1=9
7x<4x-9
Then, you subtract by 4x both sides of an equation.
7x-4x<4x-9-4x
Simplify equation.
3x<-9
Divide by 3 both sides of an equation.
3x/3<-9/3
Divide numbers from left/right.
-9/3=-3
<u><em>x<-3 is the final answer.</em></u>
Hope this helps!
Thanks!
