Question

The values of x and y satisfying the equations x/2+y/3=2, x + 2y = 8 are given by the pair.
​

Answer 1

Try all the values of x and y from 1 to 5 in 2/x+ 3/y=1. Eg x=1 y=-3. X=2 impossible. X=3 y=9. X=4 y=6. Y=5 x=5. Y=4 x=8. Y=3 impossible.....

Answer 2

Answer:

suppose x=2 & y=3

as values in 1 equation.

2/2+3/3

1+1

=2(RHS)

now equation 2

x+2y=8

x+2y=82+2y=8

x+2y=82+2y=82y=8-2

x+2y=82+2y=82y=8-22y=6

y=3

so, (x, y) is (2,3)
