Easy (yet confusing) Algebra
posted by Emily .
These problems are pretty easy, but confusing (as stated in the subject line).
2x+5x=10
3x+42x=11
I know there are supposed to be two answers for each problem, for the first problem I got 5 and for the second problem I got 7. I can't figure out the other answers for the problems. I would greatly appreciate any help I receive! Thanks!
Since it's absolute value,
2x+5=10+x OR
2x+5=10x
Just solve for x, and you get x=5, 5
Just do the same with the other!
I felt so stupid...I was solving the problems a completely different way! That's why I couldn't figure out the answers. Thanks for all your help, Mischa! :)
