Question

substitution method 2x+3y=8 and x+2y=6​

Answer 1

Answer:

x = -2, y =4

Step-by-step explanation:

2x + 3y = 8  -(i)

x + 2y = 6 -(ii)

x + 2y = 6

x = 6 - 2y - (iii)

Substituting x in (i):

2(6-2y) + 3y = 8

12- 4y + 3y = 8

12 - y = 8

-y = -4

y = 4

Putting value of y in (iii):

x = 6 - 2(4)

x = 6 - 8

x = -2

Therefore, x = -2, y =4
