Answer:
First step: Combined like terms on left side
Second step: Combined like terms on both sides
Third step: Simplified y multiplying both sides by 2/5
Solve first for the solution of the inequalities. This can be done by replacing first the inequalities sign with the equal sign.
x + y = 1
2y = x - 4
The values of x and y from the system of linear equation are 2 and -1. This means that the intersection of the lines should be at point (2, -1).
Substitute 3 to x and determine the value of y from the second inequality.
2y ≥ x - 4
Substituting,
2y ≥ 3 - 4, y ≥ -1/2
Hence, the solution to this item should be the fourth one.
I think the answer is C.
I’m not sure.
If I’m wrong I’m really sorry. Have a great day.
