Solve the inequalities in Exercieses 7 to 10 and represent the solution graphically on number line:
3x-7 > 2(x-6),6-x > 11 -2x
We have
3x-7>2(x-6)and 6-x >11 -2x
⇒3x−7>2x−12 and 6-x > 11 -2x
⇒x>−5 and x > 5
2(x-1)< x+5, 3(x+2)>2-x
5(2x−7)−3(2x+3)≤0,2x+19≤6x+47
Solve the inequalities in exercieses 17 to 20 and show the graph of the solution in each case on number line.
3x-2 < 2x +1
