Question

solve x+5 = 5 , x-y = 3​

Answer 1

$x + y = 5 \\ x = 5 - y$

Putting the value in second equation,

$x - y = 3 \\ 5 - y - y = 3 \\ 2y = 2 \\ y = 1$

Putting Value of y in first equation,

$x = 5 - 1 = 4$

∴ x = 4

y = 1

Hope It Helps:)

Answer 2

$x + 5 = 5 \\ x = 5 - 5 = 0 \\ x - y = 3 \\ 0 - y = 3 \\ - y = 3 \\ ie. \: \: \: \: \: y = - 3$
