Question

I WILL GIVE BRAINIEST
Solve the inequality 3 - 5(2x + 1) < 10.
The answers are down Below in the Picture.

Answer 1

Expand the bracket firsr by multiplying everything in the bracket by - 5 and you now have 3-10x-5<10, which simplifies to -2-10x<10
Bring - 2 over to the other side by adding 2 on both sides and now you have -10x<12. Now simply divide both sides by -10 to isolate x and you get x<-1.2, or x<-6/5 as a fraction

Answer 2

3 - 5(2x + 1) ≤ 10
3 - 10x - 5 ≤ 10
-10x - 2 ≤ 10
       +2    +2
___________
   -10x ≤ 12
Divide -10 on both sides.
x ≤ 12/-10
 x ≤ -1.2
-1.2 into a fraction is -6/5.
x ≤ -1.2 or x ≤ -6/5
