7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5
What is the result of adding -3x²-5x +1 and 8x²-2x-9?
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
-7+11x = 9-5x 11x+5x = 9+7 16x = 16 x = 1
5x + 9 = 4Subtract 9 from each side:5x = -5Divide each side by 5:x = -1
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5

4x-9(x plus 1)7-5x?
5x-1=8 Add one to each side 5x0=8+1 or 5x=9 Divide each side by 5 So x = 9/5 or nine fifths.
x2 + 5x + 3 = 9 x2 + 5x - 6 = 0 (x + 6)(x - 1) = 0 x = -6 or x = 1
9 + 5x = -4x + 63 9 + 9x = 63 9x = 54 9x/9 = 54/9 x = 6
