9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78

9x+27 = -81 9x = -81-27 9x = -108 x = -12

6x - 3y

x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0

-9x+6y = 54 6y = 9x+54 y = 1.5x+9 slope = 1.5

Do a bit of rearrangement: 1: 10x + 2 = 8y; 2: 8y = 59 - 9x so 10x + 2 = 59 - 9x so 19x - 57 making x = 3 and y is therefore 4.
