850.
68,750 = 350(75) + 50x
68, 750 = 26,250 + 50x
-26250
42,500 = 50x / 50
850 = x
86.88 kilometers is 53.98 miles
So we can get from these two equations that y = 6x + 2 = 6x + 9
6x + 2 = 6x + 9
0 = 7 , but that's incorrect, so this set has no solution.
Answer:
When 6x - 4 = 8, x = 2.
Step-by-step explanation:
6x - 4 = 8
Add 4 to both sides.
6x = 12
Divide both sides by 6.
x = 2
Proof:
6x - 4 = 8
Substitute variable.
6(2) - 4 = 8
Multiply 6 and 2.
12 - 4 = 8
Subtract 4 from 12.
8 = 8
