: My math problem is 3x + 7 - 2x = 0. How do I solve this.
What's 3x - 2x Crystal? 1x, right? ; 3 apples less 2 apples = 1 apple, right?
So (if you agree, of course), we now got: x + 7 = 0
What must you take away from 7 to be left with 0 ? 7, right? ; 7 apples less 7 apples = NO apples, right?
so (if you agree, of course), x = -7 : -7 + 7 = 0, right?
