Answer:
Step-by-step explanation:
4x + 6 + 3x + 21 = 8x + 7
7x + 27 = 8x + 7
-x + 27 = 7
-x = -20
x = 20
m<3= 8(20) + 7
160 + 7 = 167
m<1= 4(20) + 6 = 80 + 6 = 86
m<2= 3(20) + 21 = 60 + 21 = 81

The answer is A, -∞ < y < ∞
2x + 3(8 - 3x) = 3
x = 3
y = -1
2x + 3y = 3
y = 8 – 3x
2x + 24 - 9x = 3
7x = 21
y = 8 - 3(3)
