Question

substitution method 2x+y=6 2x-y+2=0​

Answer 1

Answer:

x = 1, y = 4

Step-by-step explanation:

2x + y = 6

y = 6 - 2x

2x - y + 2 = 0

2x - 6 + 2x + 2 = 0

4x - 4 = 0

4x = 4

x = 1

y = 6 - 2 = 4

Answer 2

Step-by-step explanation:

2x + y = 6

y = 6 - 2x ----- (1)

2x - y +2 = 0

replacing value from (1)

2x - (6 - 2x) +2 =0

2x - 6 + 2x + 2 = 0

4x - 4 = 0

4x = 4

x = 1

y = 6 - 2x

y = 6 - 2(1)

y = 4
