X + y = 8
x - y = 12
--------------add
2x = 20
x = 20/2
x = 10
x + y = 8
10 + y = 8
y = 8 - 10
y = -2
ur numbers are 10 and -2
-5,120
This is because you are multiplying each by -4, like 80x-4=-320
The answer is D :) hope u get an 100%!

Answer:
She made She made 100 grams of 45% sugar syrup.
Step-by-step explanation:
