Any number 1-26 should work. the expression would me x<$26.
for a line in the form of y=mx+b, the slope is m and he y intercept is b.
y= -3/4x + 3/2m = -3/4, b=3/2
Answer first number = 57 second number = 41
x= 16 + y
x + 2y = 139
16+ y + 2y =139
16 + 3y =139
16-16 +3y = 139-16
3y = 123
3/3y = 123/3
y= 41
x= 16+y
x = 16+41
x= 57
