Question

x + y =5, 3x + 2y = 11 is :

Answer 1

Step-by-step explanation:

$x + y = 5 \: \: eqn 1$

$3x + 2y = 11$

$2 \times (x + y) = 5) \\ 2x + 2y = 10$$then \: equate \: the \: equation \: 1 \: and \: 2$

$2x + 2y = 10 \\ 3x + 2y = 11$

$x = 1$

$then \: put \: the \: value \: of \: x$

$2(1) + 2y = 10 \\ 2 + 2y = 10 \\ 2y = 8 \\ y = 4$

Hope's to help you
