Answer:
x=1 y = -1/2
(1,-1/2)
Step-by-step explanation:
7x-2y=8
5x+2y=4
I would use elimination since we have 2y in one equation and -2y in the other
7x-2y=8
5x+2y=4
--------------------
12x = 12
Divide each side by 12
12x/12 = 12/12
x =1
The substitute back into equation 2
5(1) +2y = 4
5 +2y = 4
Subtract 5
5-5+2y = 4-5
2y = -1
Divide by 2
2y/2 = -1/2
y = -1/2
Answer:
Step-by-step explanation:
A=LW, given A=20, W=5
5L=20
L=4m
This year the length will be 3L=3(4)=12m
and W this year will be 2W=2(5)=10m
So the new garden will be 12m by 10m (with an area of 12(10)=120m^2)
