Question

2) If x = 1 and y = a is the solution of the equation x + 3y = 10, then what is the value of

a?​

Answer 1

Answer:

A = 3

Step-by-step explanation:

put the value in equation

1 + 3a = 10

3a = 10 - 1

3a = 9

a = 9/3

a = 3

Answer 2

Answer:

2) If x = 1 and y = a is the solution of the equation x + 3y = 10, then what is the value of a?

x + 3y = 10

1 + 3a= 10

3a=10-1

3a= 9

a=9/3

a = 3
