4x+35-2x+25 = 6 2x+60 = 6 2x = 6-60 2x = -54 x = -27

4x+9=2x-6 2x=-15 x=-7.5 x equals -7.5.

-6 + 4x + (9-2x) = -6 + 4x + 9 - 2x = [ 3 + 2x ]

x=4

2x-3=4x+9 -2x-12=0 2x=-12 x=-6

-2x-6= -2x-6Another answer:-2x-6 = 2x+6-2x-2x = 6+6-4x = 12x = -3

2x + 6 - 6x = 30= 6 - 4x = 30= -4x = 24= 4x = -24= x = -6

7x + 6 - 4x = 5 + 2x + 7 subtract 6 from both sides and combine the 5 and 7 on the right: 7x - 4x = 2x + 6 subtract 2x from both sides and combine the 7x and -4x on the left: x = 6

4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.

5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2

(4 + 2x) - (-2x + 1) = 13 + 6 4 + 2x + 2x -1 = 19 4x +3 = 19 4x = 19 - 3 4x = 16 therefore x = 16/4 x = 4

4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x

They are parallel lines.

If: 1-2x-5 = 4x+2 Then: -2x-4x = 2-1+5 And: -6x = 6 So: x = -1

It is a contradiction! 6x - 4x - 6 = 2x 2x - 6 = 2x -6 = 0 false

4x + 6 = 6x - 12-4x -4x6 = 2x - 12+12 +1218 = 2xx=9

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

-2x + 6 <= 4x + 18 -2x <= 4x + 12 -12 <= 6x -2 <= x

In standard form it is 4x - 4y = 6 or 2x - 2y = 3

4x - 7 = 2x + 5Add 7 to each side ==> 4x = 2x + 12Subtract 2x from each side ==> 2x = 12Divide each side by 2 ==> x = 6

3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3

4x=-10 x=-2.5

y = 2x + 3

4x+2y = 6 2y = -4x+6 y = -2x+3 Slope = -2

4x + 2y = 6 (first equation x 2) 4x + 2y = 6 (second equation rearranged) No unique answer exists
