(9x)2 +9x/(45x)2 +81= 9+9x/86
9x squared plus 16 = 0 factored is plus and minus 4/3 i.

x - 10x = 9x, so 9x + 3 = 0, so 9x = -3 so x = -1/3

-38-10x = 9x+19 -38-19 = 9x+10x -57 = 19x |: 19 -3 = x Therefore x equals -3
x2 + 9x2 = 10x2
9x + 1x = 10x.

10x = 9x -25 10x -9x = -25 x = -25
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

-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
