# Completely lost in this simultaneous equationWatch

#1

I've gotten to the factorising part and I don't know where to go from that stage

These are my stages

I halved the equation

Not sure what to do next, this is non-calculator by the way

x = 3/5
x = 1

You take each bracket and flip the sign then divide the right number in the bracket by the coefficient of x of the same bracket.

Then put these two answers into either of the two equations to find both y values.

It would probably be smart to check if her working up to that factorisation was correct. (It wasn't)

Ah yes, ha didn't think I'd need to do that, cheers for the edit.
