Solving equation 1 and 2 we get 4x=19 x=19/4 2x3y=17 2×19/43y=17 3y=1719/2 3y=15/2 y=5/2 So x=19/4 and y=5/2
2 x 3 y 17 2 x 2-3 y 1 5- A x 2y = 17 x y = 2 Subtract the second equation from the first, term by term x x 2y (y) = 17 2 or 3y = 15 Divide both sides by 3 y = 5 Put this back into the first equation x 2*5 = 17 x 10 = 17 x = 17 10 x = 7 B 4x 5y = 11 2x 6y = 1677 3 x3 10 = x3 x7 78 = 2x 3 5 x 3x 9 79 = 6 x1 _ 12 5 3x 80 30 x 2 5 2x 5 = 4 x 81 1 x1 x = x1 3 62x 18
