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

10x=x 9x=0 x=0

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

9x+27 = -81 9x = -81-27 9x = -108 x = -12

x2=9x-20 x2-9x+20=0 Factor: (x-4)(x-5)=0 x={4,5}

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

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

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

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

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

9x + 1x = 10x.

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.

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

-171 = 19x so x = -9

10x=x 9x=0 x=0

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