Question

Solve the pair of linear equations 3x + 2y = 8 and 2x + 3y = 7. The value of (x, y) is​

Answer 1

3x + 2y = 8---------------(1)

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

add equation(1) and (2)

3x + 2y = 8---------------(1)

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

––―――–––-

5x+5y=15

divide both the side by 5

x+y=5----------(3)

subtract eq (1) and (2)

3x + 2y = 8---------------(1)

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

- - -

––––––––--

x-y=1------------(4)

add eq (3) and (3)

x+y=5--------(3)

x-y=1----------(4)

---------

2x=6

x=6/2

x=3

putting x=3 in eq (3)

x+y=5--------(3)

3+y=5

y=5-3

y=2

Answer 2

Answer:

the value of x is 1 and y is 0
