Answer:
The given equations are
4x+2y=5 ...(i)
x−2y=0 ...(ii)
from (ii) equation, x=2y
∴(i) becomes, 8y+2y=5⇒10y=5⇒y= 21
∴x=2y=2×
21=1
Hence, x=1 and y=2
hope it helps you ❣️

Answer:
4x+2y = 5 ....... equation (1)
x-2y = 0 ...... equation (2)
By elimination method,
4x+2y = 5 .... (1)
x-2y = 0 ....(2)
therefore, x = 1
now, substituting x = 1 in equation (1)
4(1)+2y = 5
4+2y = 5
2y = 5-4
2y = 1
therefore,
y = 1/2
ANS : x = 1 and y = 1/2
