Question

solve the following 3 x minus 4 Y is equal to 10 4 x + 3 Y is equal to 5

Answer 1

3x-4y=104x+3y=5
-104x+3x-4y-3y=5

101x-7y=5
101x=5+7y equation 1,
ab equation one se x ka value nikal do usme se x ya y mein se kisi ek ko constant rakh lo aur value nikal lo

Answer 2

$3x - 4y = 10 \\ 4x + 3y = 5 \\ in \: order \: to \: use \: elimination \: \\ method \ the \: coefficients \: \\ should \: be \: same for \: any \: one \: \\ variable \\ 12x - 16y = 40 \\ 12x + 9y = 15 \\ on \: subtracting \: u \: get \: \\ - 25y = 25 \\ y = 1 \\ on \: substituting \: y \: value \: in \: any \: one \: equation \\ 12x - 16( - 1) = 40 \\ 12x = 24 \\ x = 2$
