Question

solve 3x+y=4,2x-y=6​

Answer 1

Answer:

$3x + y = 4 \: \: \: \: - (i)\\ 2x - y = 6 \: \: \: \: - (ii)\\ - - - - - - - \\ 5x = 10 \\ or. \: \: x = \frac{10}{5} \\ or. \: \: x = 2\\ - - - - - - - \\( i) \: equation \: we \: replace \: (x) \: to \: 2 \\ 3.2 + y = 4 \\ or. \: \:6 + y = 4 \\ or. \: \: y = 4 - 6 = ( - 2)$

X = 2 and Y = (-2)

It's your answer..
