Answer 2

Answer:

2x + y = 11

∴ y = 11 - 2x                                               $Equation$ $1$

= x + y = 8                                                  $Equation$ $2$

= 11 - 2x + x = 8

= x = 3

∴ $Value$ $of$ $"x"$ $is$ $3.$

Substituting x = 3 in $Equation$ $2$

we get

y =  11 - 6 = 5

∴ $Value$ $of$ $"y"$ $is$ $5.$
