Question

Using substitution and elimination method solve
x+y=1
x+2y=7

Answer 1

Step-by-step explanation:

✏Given here

↪X + y = 1......(1)

↪x+2y = 7.......(2)

[ by (1) , x = 1-y , keep in (2) ]

↪1-y +2y = 7

↪1+y = 7

↪y = 6

[ by (1) ]

↪x + 6 = 1

↪x = 1-6

↪x = -5

⏩Thus:-

Value of X = -5

Value of Y = 6
