3-6x = 15 -6x = 15-3 -6x = 12 x = -2

3-6x=15 or,6x=3+15 or,6x=18 or,x=18/6 or,x=3 [Ans].

-15 = 6x + 3 - 3-15 = 6x (3 - 3 = 0)-2.5 = x (-15/6)

x=3 becaus: 6x=x+15 5x=15 (-x) x=3 (divided by 5)

5x+15 = 6x-10 5x-6x = -10-15 -x = -25 x = 25

3-6x = 15 -6x = 15-3 -6x = 12 x = -2

-15 = 6x + 3 - 3-15 = 6x (3 - 3 = 0)-2.5 = x (-15/6)

3x=6x-15 ....you want to take 6x and put it on the other side of the = sign. To do that you do the opposite. So you would subtract since 6x is a positive number. so then the equation is 3x-6x=-15. 3x-6x = -3x which makes the equation -3x=-15. Then you would take -3 which is being multiplied by x and do the opposite operation on the other side. so -3 divided by -15 equals 5. which makes the equation now x=5. So then 5+8=13

x=3 becaus: 6x=x+15 5x=15 (-x) x=3 (divided by 5)

5x+15 = 6x-10 5x-6x = -10-15 -x = -25 x = 25

4x-1 = 6x-15 4x-6x = 1-15 -2x = -14 x = 7

x+15+(-15)=6x+(15+(-15)=6x+(15-15)=6x+(0)=6x+0=6Add/subtract 0 from both sides,x=6

6x - 12 = 3x + 15 3x = 27 x = 9

If: 16x-15-6x = 13 Then: 10x = 28 And: x = 2.8.

9x+6 = 6x+15 9x-6x = 15-6 3x = 9 x = 3

6x - 3y = 6 y= 2x + 5 replace 2x + 5 for y into the first equation 6x - 3y = 6 6x - 3(2x + 5) = 6 6x - 6x - 15 = 6 0 - 15 = 6 -15 = 6 False So the system has no solution.
