Solve the inequality |4 - 3y| inequality 7 Solve the inequality |4-3y/5|+4 inequality 7

Solution

3)
|4-3y|>= 7
(4-3y) >= 7 or -(4-3y)>=7
3y<=-3 or -4 + 3y >=7
y<=-1 or 3y >=11
y<= -1 or y>=11/3

y should be less than or equal to -1 or it should be greater than equal to 11/3

so,
y = (-inf,-1] U [11/3 ,inf)
