Title: Can you solve for a variable in an expression? Explain your answer? Post by: Julaaro on Jan 12, 2013 very easy to do, just isolate it, and .... well here, 5x+3=5 instead, reduce 3 on both sides to move it, 5x=2 then divide by 5 to undo x=2/5 though that equals a fraction, they usually don't in basic algebra
Title: Can you solve for a variable in an expression? Explain your answer? Post by: smmrwds on Jan 12, 2013 Well, in an expression you can't really solve for a variable, because there is no equality or inequality sign, you can only simplify it. Like:
2(5+3)-1 would be simplified to 15 2x+4x-2+4 would be simplified to 6x+2 In an equation, you can solve for a variable because there is an equality or inequality sign. Like: 6x=3 where x=2 |
