Answer:
y = -x +4
Step-by-step explanation:
2x+5y = 3y+8
Subtract 3y from each side
2x+5y-3y = 3y-3y+8
2x+2y = 8
Subtract 2x from each side
2x+2y -2x = -2x+8
2y = -2x+8
Divide by 2
2y/2 = -2x/2 +8/2
y = -x +4
Given :
If a number is tripled , it give same result as 28 is added to.
To Find :
We need to find that number.
Solution :
Let, the number is x.
Mathematical equation of the given scenario is :
3x = x + 28
3x - x - 28 = 0
2x - 28 = 0
x = 14
Therefore, the which give such result is 14.
c = 150 -8s
Step-by-step explanation:
Each "snack" was 8 pieces of candy, and there were 18 of them (plus 6 candies) to start with. Hence the starting number was ...
... 18×8 +6 = 144 +6 = 150
Each snack reduced that number by 8, so the candies remaining are
c = 150 -8s
