Answer:
y = 15
Step-by-step explanation:
x + y + z = 45 → (1)
Given
y = (x + z)
Multiply both sides by 2 to clear the fraction
2y = x + z ← substitute into (1)
2y + y = 45
3y = 45 ( divide both sides by 3 )
y = 15
23 because if u add bothe of them up
Answer: 74

48+75+25/2
Answer:
x and y = 0

Step-by-step explanation:
Multiply the top equation by 3 to make the -x a -3x instead.
Then do the top equation - the bottom equation
At this point you should be left with x
