X + y = 76
x - y = 20
------------add
2x = 96
x = 96/2
x = 48
x + y = 76
48 + y = 76
y = 76 - 48
y = 28
ur numbers are : 48 and 28
<h2>sorry I can't help you to solve the equation</h2>
They are all the x points on the graph like the range is the y

Find the area of trapezoid.
1/2(6+10)(3) = 24
Now multiply 24 by $4 to find the total cost.
24 * 4 = 96
