Question

x + y = 1 and 3x + 2y = 6​

Answer 1

Step-by-step explanation:

$x + y = 1..........eq.1 \\ 3x + 2y = 6......eq.2 \\ from \: eq.1 \\ x = 1 - y \\ putting \: the \: value \: of \: x \: in \: eq.2 \\ = 3(1 - y) + 2y = 6 \\ = 3 - 3y + 2y = 6 \\ 3 - y = 6 \\ - y = 3 \\ y = - 3 \\ \\ x = 1 - y \\ x = 1 - ( - 3) \\ x = 1 + 4 \\ x = 5$

Answer 2

Answer:

x=4 and y=-3

Step-by-step explanation:

x+y=1

x=1-y

putting value of x in 2nd equation...

3x+2y=6

3(1-y)+2y=6

3-3y+2y=6

3-y=6

3=6+y

y=3-6

y=-3

putting value of y in 1st equation..

x+y=1

x+(-3)=1

x-3=1

x=4

Hope it helps you...
