Answer:
x = 7
Step-by-step explanation:
since we know y = 4, we can plug this into the equation to find x

8x - 2(4) = 48
8x - 8 = 48
8x = 56

Answer:
it A
Step-by-step explanation:
5+1x=3(x-7)+6
5+1x=3x-21+6
5-5+1x=3x-15-5
3x-1x=3x-3x-20
-2=-20
-20/-2=10
X=10
After the first day, 1/3 of the original amount remained:
... (1/3)·45 = 15
After the second day, 2/3 of that amount remained:
... (2/3)·15 = 10
