Question

3. Draw the graph of the solution set of the inequations:
2x+y ≤ 2, x-y ≤ 1, x+2y≤8, x≥0 and y≥0​

Answer 1

Remember that the absolute value operation turns negative values into positive ones. So if the argument within the absolute value is more than five or less :

2x-1>5

2x>6

x>3

2x-1<-5
