The most useful thing we can do for you is to point out mistakes you make. If we show you what to do, you won't know what to avoid, because we're unlikely to think of mentioning an error that results from your particular wrong ways of thinking.I need help solving this from start to finish i have a test tomorrow and i'm lost
30 - 2a = 8 - 5(a - 8)
Hi. We can't solve for a variable, as long as it appears inside grouping symbols. Use the distributive property, to multiply (a-8) by -5. Doing that will get rid of the parentheses. You can then proceed to combine like-terms.30 - 2a = 8 - 5(a - 8)
