Question

4. If x=1 and y=a is the solution of the equation x+3y=10 then find a.​

Answer 1

Answer:

a= 3

Step-by-step explanation:

x = 1 , y = a

putting values

1 + 3a = 10

3a = 10 - 1

3a = 9

a = 3

Answer 2

a=3

Step-by-step explanation:

soln

x=1. y=a

x+3y=10

1-3a=10

3a=10-1

3a=9

a=9/3

a=3

hence a=3
