Solve the inequalities in Exercieses 7 to 10 and represent the solution graphically on number line:
5x +1 > -24, 5x -1 < 24
SOl: We have
5x+3 1 > -24 and 5x -1 < 24
⇒5x > -25 and 5x < 25
⇒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.
5x−3≥3x−5
Solve the inequalities and represent the solution graphically on number line: 2(x – 1) < x + 5, 3(x + 2) > 2 – x
