[edit]algebra 1
[edit]i need help on this problem:
find three solution on for this equation using -1,0,1 for x: 5x+7y=8
- To do this question, you'll need to substitute those three numbers into x one at a time. So firstly, let x = -1. Therefore: 5(-1)+7y=8 which is -5+7y=8. Then you can solve for y. See this link if you need help on solving equations. Then do the same thing, but this time with x=0, then x=1 and you'll have three solutions. Hope this helps. - Akamad 22:30, 3 February 2007 (UTC)
