iluvmathw/mr.hackett: how do u go from 5y+5=45x+315 to -9x+5y=58??? PLEASE HELP
Hello iluv...
First yuo look for a common factor, a number or a letter that goes into all the terms.
5 goes into everything
Divide both sides by 5
Now the answer doesn't have any xs on the right hand side (RHS) so you will need to take them away from the RHS but you will need to take them away from the LHS as well so that your equation stays 'balanced'.
You should be able to do it now.
