If `(a ,\ 4)` lies on the graph of equation `3x+y=10` , then the value of `a` is
(a) 2
(b) 1
(c) 3
(d) 4

Text Solution

Verified by Experts

"`(a ,\ 4)` lies on the graph of equation `3x+y=10`
so `x=a,y=4` satisfies the equation
putting thwe values
we get
`3(a)+4=10`
`3a=6`
so
`a=2`
so,ans is (a) 2"
