Step-by-step explanation:
Step: Solve−3x+y=15 for y:
−3x+y=15
−3x+y+3x=15+3x (Add 3x to both sides)
y=3x+15
Substitute 3x+15 for y in−3x+7y=−3:
−3x+7y=−3
−3x+7(3x+15)=−3
18x+105=−3(Simplify both sides of the equation)
18x+105+−105=−3+−105 (Add -105 to both sides)
18x=−108 divide both side by 18
x=-6
9514 1404 393

Step-by-step explanation:
The total of ratio units is ...
6 + 3 + 8 = 17
The difference between the Charlie's ratio units and Adrian's ratio units is ...
8 - 6 = 2
That is, the total number of ratio units is 17/2 = 8.5 times that difference.
The actual difference is 12 sweets, so the total number of sweets is ...
8.5 × 12 = 102 . . . . total sweets
