myko is right, but when you move a number to the other side of the eual sign you need to change the sign of the number itself. 4 becomes -4 and -4 becomes 4

If you're getting the "X's" on one side then make sure you include the x. You're combining like terms. So it would be +3x under the -3x and the -7x. But you got it right so far after you get there your going to combine the +2 and the -22.

-3x + 2 = -7x-22
now bring like terms at one side so terms with variable lets say the ones with "x" bring them together and numbers together ;) so
-3x+7x=-22-2
4x=-24
now divide both sides by 4 and you will have
x=-6
\[\frac{ 4x }{ 4 }=\frac{ -24 }{ 4 }\] so x= -6 ;)

nope i did , just bring 4x in the left so sign will be changed and take +2 on the right so sign will be changed and it will be +4x and on the right it will be -2 because sign gets interchanged
