Answer: x = 12 and y = -8
Explanation:
x + y = 4
4x + 3y = 24
———————
-3(x + y = 4)
4x + 3y = 24
———————-
-3x - 3y = -12
4x + 3y = 24
———————
x = 12
If x = 12
x + y = 4
12 + y = 4
y = -8
I don’t get it but I would like to help tho

It would be a five
Step-by-step explanation:
Answer:
A. √500
Step-by-step explanation:
Since 500 = 5·100 = 5·10² you can move the 10² out of the √ as 10.
Hence 10√5 = √500
So we're using these rules:
√a·b = √a·√b
and of course
√a² = a (a>0)
Answer:
1) l=15 2) w=10
Step-by-step explanation:
l=w+5, 2l+2w=50
2(w+5)+2w=50
4w+10=50
w=10, l=15
