HOPE IT HELPS U.
also with x=1 &y=2
3(2)=a(1)+7
6=a+7
a=-1

Hi !
Here we are given 2 values of x and y each :
x = 3 or 1
y = 4 or 2
We can use any 1 from each value of x and y to get the value of "a"
lets take x = 1 ,y = 2
3y = ax + 7
3(2) = 7a + 7
7a + 7 = 6
7a = -1
a = -1/7
--------------------------------------------------------------------------------------
x = 3 , y = 4
3y = ax + 7
12 = 3a + 7
3a= 5
a = 5/3
