Solve the system of equations and choose the correct order pair.

Aneli [31]

$(2x + 4y = 14) \div 2 = x + 2y = 7$
making x the subject
$x = 7 - 2y$
substitute into second equation
$3(7 - 2y) + 12y = 51$
by solving, y=5

substitute into first equation
$2x + 4(5) = 14$
by solving, x=-3

Therefore the ordered pair is (-3,5)
