Question

How many solutions does 3 (x-1)=x+7 have

Answer 1

3x -1 = x + 7 and collect like terms
3x-x = 7+1
2x=8
X=5

Answer 2

Do you know how to solve algebra? If so just solve for X. If you get an invalid equation then 0 solutions, if you get x equaling 1 number then 1 solution, if you get x equaling 2 numbers then 2 solutions, and so on.
