Question:
I need to find the following equation.
4x - [2x -(3x - 2)] = 13

I thought the answer was -15 Would you show me how to work this problem?

When you have brackets or parentheses in an algebra problem you need to work from the inside out. The left side of your expression is 4x - [2x - (3x - 2)] and hence you need to start with

Working my way out, one step at a time I get

then

and

and then finally

Thus the equation that you have

can be rewritten

Now add 2 to both sides to get

Lastly divide both sides by 5 and the solution is
