Question

2x+3y=1, 3x-y=7 then find the values of
(x, y)​

Answer 1

Step-by-step explanation:

we will use elimination method

2x+3y=1 ----- (1)

3x - y =7 -------(2)

now multiply by 3 in (2)

we get ,

9x -3y=21

2x+3y =1

---------------

11x = 22

x= 2

now put x=2 in (1)

2×2+3y=1

3y=1-4

y=-3/3

y=-1

Answer 2

Answer:

x = 2

&

y = -1

Step-by-step explanation:

As shown

• 2x = 1-3y
• x = 1-3y / 2

• 3x = 7 + y
• x = (7+y)/3

Then

• (1-3y)/2 = (7+y)/3
• 3 - 9y = 14 + 2y

So

y = -1

If,

• 2x = 1 - 3y
• x = (1 - 3y) / 2
• x = {1 - 3(-1)} / 2
• x = (1 +3) / 2

So

x = 2
