8x-7 plus 2x equals 6 plus 5x plus 2?

2x + 3x + 6 = 5x + 6

5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14

3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3

DIE

if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7

5X + 6 = 2X + 15 -2X -2X 3X + 6 = 15 -6 -6 3X = 15 ---- ----- 3 3 x = 5 im so smart.

5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5

x=6Solution:x + 2x + 14 = 5x + 214 - 2 = 5x - 3x12 = 2xx = 12/2 = 6

8x + 5x + 2x + 4x = 114 19x = 114 x = 6 then 5x + 3 = 5*6 + 3 = 33

5x - 2x = -5 - 1 ie 3x = -6 so x = -2

-2(5x+3)-2x<-3(2x-4)+2

x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3

3x+5=4-2x+6 5x=4-1 5x=3 x=3/5

5x+2 = 3x-6 5x-3x = -6-2 2x = -8 x = -4

5x+(6-3x)+8=5x+6-3x+8=2x+14 2x + 14

5x+6-2x=-5-x 3x+6=-5-x 4x=-11 x=11/-4

3x + 4 = 5x - 6 -3x -3x 4 = 2x - 6 +6 +6 10 = 2x 5 = x

Point Slope Form - Y=.5X+1.5

2X + 5Y = 6 5Y = - 2X + 6 Y = - 2/5X + 6/5 ----------------------------------and 5X - 2Y = 8 2Y = - 5X + 8 Y = - 5/2 + 4 ------------------- Look like intersecting lines, though not perpendicular

Factorise: 5x2 + 2x - 192 = (x - 6)(5x + 32) = 0; whence, x = 6 or -6.4.

3x-4=5x+6 gives: 2x=-10 which gives x=-5

3(x + 2) = 5x - 12 3x + 6 = 5x - 12 6 = 2x - 12 6 + 12 = 2x x = 9

6-3x = 5x-10x+10 6-3x = -5x+10 -3x+5x = 10-6 2x = 4 x = 2

3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
