9x-17=6x-8, could someone help me solve and tell me when do i need to change the problem from addition to subtraction

Question

anonymous · Answer

You need to subtract 6x from both sides first

anonymous · Answer

ok now 3x-17=-8...add 17 to both sides?

anonymous · Answer

yes

anonymous · Answer

You always do the opposite sign of what you are trying to get rid of when you add or subtract.

Hint.. When x's are on both sides I ALWAYS get rid of the smallest x, that way you always have a POSITIVE x to work with after that.
