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
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
