4x-2=18
-2 on both sides
4x=16
divid by 4 on both sides
x= 4
Answer:
C
Step-by-step explanation:
when x=0, y=0, so B is impossible
when X=2, Y=1,
and thus C is correct
Answer:
a. 
b. x = 10
Step-by-step explanation:
a. The number of home runs hit by Jack last season = x
It is given that Henry hit 3 more than half as many home runs as Jack hit.
Half of the runs hit by Jack = 
3 more than half the runs = 
So, the number of home runs hit by Henry = 
But, it is given that Henry hit a total of 8 runs.
Therefore, 
b. 
Subtract 3 from both sides.

= 5
x = 5 × 2
= 10
Hence, Jack hit 10 runs in the last season.
