1. 7x + 9 = 48
7x = 58 - 9
7x = 49
X = 7
Answer:
x=5, y=4. (5, 4).
Step-by-step explanation:
2x-3y=-2
4x+y=24
------------------
-2(2x-3y)=-2(-2)
4x+y=24
----------------------
-4x+6y=4
4x+y=24
--------------
7y=28
y=28/7
y=4
4x+4=24
4x=24-4
4x=20
x=20/4
x=5
The inequality is:
48 c + 200 ≤ (the maximum load allowed on the elevator) .
