Answer:
h = 14
Step-by-step explanation:
9=h-5
9 + 5 = h -5 +5
14 = h
Answer:
Step-by-step explanation:
First write the question as an equation
x+y = -5
2x+y = -2
From the given equations, we can create a third one.
x+y+2x+y = -7 or 3x+2y = -7
Use trial and error method for the possible values x and y
We know that at least one of these two have to be negative.
x can be 1, in which case y has to be 5.
Check this for
x+y ≠ -5
x can be -1
Try another one where x = -1 and y has to equal -2
Check this
X
x+y = -5
but,
2x+y ≠ -2
Another one,
Answer:
A
Step-by-step explanation:
Answer:
y = 40, x = 9
Step-by-step explanation:
2(3y)+2(2y-20)=360
y = 40
2x=18
x = 9
