Question

write four solution for this3=2x+y

Answer 1

2x + y = 3

=> y = 3 - 2x

First case : X = 1

=> y = 3 - 2 ( 1 )

=> y = 3 - 2 = 1

Hence x = 1, y = 1

Second case : X = 2

=> y = 3 - 2 ( 2 )

=> y = 3 - 4

=> y = ( - 1 )

Hence x = 2, y = ( - 1 )

Third case : X = 0

=> y = 3 - 2 ( 0 )

=> y = 3 - 0

=> y = 3

Hence x = 0, y = 3

Fourth case : X = ( - 1 )

=> y = 3 - 2 ( - 1 )

=> y = 3 - ( - 2 )

=> y = 3 + 2

=> y = 5

Hence x = ( - 1 ) , y = 5

These are the four solutions.
