7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5
x = 1
[9x-5x+1] + [16x-2x-9] [4x+1] + [14x-9] [18x2+8]
5x + y = 6 so that y = 6 - 5x Also x +2y = 1 so that x + 2*(6-5x) = 1 or x + 12 - 10x = 1 => 9x = 11 or x = 11/9 and then y = 6 - 5x = 6 - 55/9 = -1/9
4x-9(x plus 1)7-5x?
