8x = -11y - 16 first equation 8x + 11 y = -16 subtract 11y from both sides 2x + 3y = -4 second equation -8x -12y = 16 multiply by -4 . we have 8x + 11y = -16 -8x -12y =16 ___________________ -y = 0 add the equations to eleminate x y = 0 let y = 0 in first equation 8x = -$11\times0$ -16 8x = -16 x = -2 divide both sides by 8
