They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
Answer:
x=1
y=-1/2
Step-by-step explanation:
x+2y=0....(1)
10y=-5.....(2)
From (2) we can find y.
y=-5/10
y=-1/2
Use that in (1)
x+2*(-1/2)=0
x-1=0
x=1
8.52624 is not the same as 5.85, 63.4 , and 27.5.
Hope this Helps!!
