Question

if 2x+y=5 and x-2=0 then find the value of y

Answer 1

2x+y=5 ...... (EQ 1)
x-2=0
x= 2
Put x in EQ 1
2x+y=5
2(2) +y=5
4+y=5
y=1

Answer 2

if 2x+y=5 and x-2=0 then find the value of y
we have given x - 2 = 0 so, x = 2
put the value of x in the given equation
2x+y=5
2*2+y = 5
4+y = 5
y = 5-4
y = 1
