Homework Help: algebra

Posted by thawk on Saturday, November 13, 2010 at 10:47am.

Help me please I get confused with the positives and negatives. Please be kind to check my work and let me know where am I going wrong

-4x + 10 = 58
-4x + 10 -10 = 58 -10 (is it - or +10?)
-4x = 48 or 68 (do i add 58&10 or sub?)
-4x/-4 = 48/-4 or 68/-4 (is the 4 -or+)
x=12 or x=68

These are my confusions. Please help me. Thank you very much

-4x=48 you subtracted 10 from each side.
x=-12 you divided both sides by -4

You have to do the same thing to both sides.
