Stuck with simultaneous equations? Here ya go, a step by step guide on how to work them out. Hope it helps.

1) 4x + 7y = 10
2x + 3y = 3

The whole trick in working out simultaneous equations is figuring out a way to eliminate all but one of the variables so that it can be solved. Once you get one, you start working backwards to get the other(s). While this operation can be accomplished in…

@smellslikek-pop You multiply it by two so that you can subtract the the equations and terminate the x value else the whole thing just gets messy. That make sense?
