The given terms can be simplified to: 20x+20

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

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

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

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.

9x + 1x = 10x.

-171 = 19x so x = -9

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

200

9x2 - 28x + 20 = 9x2 - 18x - 10x + 20 = 9x(x - 2) - 10(x - 2) = (9x - 10)*(x - 2)

10x + (8-x) = -19 10x + 8 = x - 19 10x = x - 27 9x = 27 x = 3

x=5.2

10x=x 9x=0 x=0

-20 + 9x = -17-20 + 17 = -9x-3 = -9x |: (-9)0.333... = xx = 0.333...

The slope is 0.

it equals 13X.

3x-2x-3x+6 = 5-10x+9x-5 Clean up both sides (the fives on the right cancel out) -2x + 6 = -1x add 2x to both sides 6 = x ■

2x(2x2 - 9x + 5)

If x equals 10 and y equals 10, then 9x plus 8y equals 170.

x squared plus 9x plus 20.

10x+3 < 9x-6 (subtract 9x from both sides to give..) if and only if x+3 < -6 (subtract 3 from both sides to give ..) if and only if x < -9

9x+3-25 = 4x-2 5x = 20 x = 4

It is 9x
