Question

If the point (a,3) lies on the graph of the equation 5x+y=8, then a=

Answer 1

a = 1

Explanation:

The given equation is:

=> 5x+y = 8

Also,

Point = (x,y) = (a,3)

So, x = a , y = 3

Putting this in the above equation

=> 5(a)+3 = 8

=> 5a = 8-3

=> 5a = 5

Dividing both sides by 5

=> a = 1
