Answer:
x=3, y=23
x=6, y=41
x=8, y=53
x=9, y=59
Step-by-step explanation:
x=3, y=6(3)+5
y=18+5
y= 23
x=6, y=6(6)+5
y=36+5
y= 41
x=8, y=6(8)+5
y=48+5
y=53
x=9, y=6(9)+5
y=54+5
y=59
To solve for x, you first add 5 to both sides so it remains equal.
3 + x = 2
Then you simply subtract 3 on both sides.
x = -1
Substitute your solution into the equation and see it is true.
|3+(-1)) - 5 = -3
The equation is true, therefore your answer is: x = -1
Answer:
4 trucks per hour
