Question

if x=1,y=a is the solution of equation x+y=18, then find a​

Answer 1

Step-by-step explanation:

x + y = 18

1 + a = 18 [ a = y ] given

a = 18 - 1 = 17

a = 17

Answer 2

Answer:

Given,

x = 1 , y = a and x + y = 18

So, we put the values of x and y in the given equation ,

1 + a = 18

a = 18 - 1

a = 17

Now the value of a is 17 .
