Question

The value of x and y in the pair of equation 2x+y=5 and 3x+2y=8 are A) x=2,y=1
B) x=-2,y=-1
C) x=-2,y=1
Which is the correct answer ?

Answer 1

Step-by-step explanation:

put values or simply solve:

$2x + y$

multiply by 2

$4x + 2y = 10$

$3x + 2y = 8$

subtract

$x = 2$

substitute x in eqn 1

$4 \times 2 + 2y = 10$

$2y = 2$

$y = 1$

thus x=2 and y=1

Answer 2

Step-by-step explanation:

(2x+y)*2

= 4x+2y =10____1

(3x+2y)*-1

=. -3x -2y=-8_____2

solving the equation 1 and 2

we get x=2

substituting X=2 in equation 1

we get y=1
