24x +8y ≥ 20

3x - 6y > 24

First, express both equations in slope-intercept form

y= mx+b

Where:

m= slope ( rise (y) / run (x))

b= y-intercept (where the line crosses the y axis)

Solve for y:

24x +8y ≥ 20

8y ≥ -24x +20

y ≥ (-24x +20 ) / 8

y ≥ -3x + 2.5

3x - 6y > 24

-6y > 24- 3x

y < (24 -3x) / -6

y < 1/2x -4

System:

y ≥ -3x + 2.5

y < 1/2x -4

Solution = the area where the 2 solutions overlap (blue+ red)
