amo_mea_filiis. Posted February 29, 2016 Share Posted February 29, 2016 I have no idea why we can't this. Just one of those days. Help? :) 2(n-5)=-2(-3n+5)+6 Quote Link to comment Share on other sites More sharing options...
wapiti Posted February 29, 2016 Share Posted February 29, 2016 2(n-5)= -2(-3n+5)+6 2n - 10 = 6n - 10 + 6 -4n = 6 n = -3/2 Quote Link to comment Share on other sites More sharing options...
forty-two Posted February 29, 2016 Share Posted February 29, 2016 (edited) 2(n-5)=-2(-3n+5)+6 ugh, missed a negative, trying again. Try 2: 2(n-5)=-2(-3n+5)+6 n-5 = -(-3n + 5) + 3 n-5 = 3n -5+3 n = 3n + 3 -2n = 3 n = -3/2 check: 2(-3/2-5)=-2(-3(-3/2)+5)+6 -3-10 = -2(9/2 + 5) + 6 -13 = -9 - 10 + 6 -13 = -13 Yea, finally works ;).

SparklyUnicorn Posted February 29, 2016 Share Posted February 29, 2016 2(n-5)= -2(-3n+5)+6 2n - 10 = 6n - 10 + 6 -4n = 6 n = -3/2 -2 times -3n was hard to see the negatives.... 1 Quote Link to comment Share on other sites More sharing options...
