QUOTE(angelbabystar @ Oct 6 2005, 6:10 PM) 2(a-8)+7=5(a+2)-3a-19  1. Distribute the 2 across the parentheses and the 5 across the other pair of parenthesis 2. You get 2a-16+7=5a+10-3a-19 after you distribute. 3. Combine like-terms. I.E. add all the terms with the a after them and all the regular numbers. Remember, if you're moving a number across the equal sign, it changes signs (so if it's negative and you move it to the other side, it will be positive and vice versa). 4. You should get -6a=-18 5. Divide by -6 on both sides. 6. a= ___ 7. And there you have it! I hope that made sense...
