Q20 of 65 Page 122

Solve the inequalities in Exercises 17 to 20 and show the graph of the solution in each case on number line:

We have,


Solving the given inequality, we get:





= 15x ≥ 2 (4x - 1)


= 15x ≥ 8x -2


= 15x -8x ≥ 8x -2 -8x


= 7x ≥ -2



Now, the graphical representation of the solution is as follows:
