6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
8x-4 = -7+5x 8x-5x = -7+4 3x = -3 x = -1
5x - 1 = 24 5x - 1 + 1 = 24 + 1 5x = 25 5x/5 = 25/5 x = 5
Add 4x - 2 to each side: 5x = 5 x = 1

6x2+5x+1 = (3x+1)(2x+1) when factored
1. 6x - 5y = 22 2. 5x - 9y = -1 1 times 5: 30x - 25y = 110 2 times 6: 30x - 54y = -6 Subtract : 29y = 116, so y = 4 and x therefore = 7
6x+1-x-3 = 8x-5-8 5x-2 = 8x-13 5x-8x = -13+2 -3x = -11 x = 11/3
2(1 - 3x + 6) = -x 14 - 6x = -x 14 - 6x + 6x = -x + 6x 14 = 5x 14/5 =5x/5 14/5 = x
One factor of 6x² + 5x - 11 is (x - 1).
x2 + 5x - 6x = x2 - x = x(x - 1) which is zero when x = 0 or x = 1
y=-5x-17 y=x-1 -5x-17=x-1 -17=6x-1 -16=6x 2 2/3=x then you plug in the x for each of the equations to make sure that the answer you get is correct. ;)
