Question: Solve for x: 3(x+1)+4=5x+7-2x .
3(x+1)+4=5x+7-2x -- multiply out the brackets.
3x + 3 + 4 = 5x + 7 - 2x -- group all the x-terms on one side and teh constant values on the other.
3x - 5x + 2x = 7 - 3 - 4 -- simplify.
0 = 0
This means that there is no unique solution. In other words, the equation is valid for all values of x.
