Hi
I have been trying to understand this simultaneous equations for along time but I just dont understand i dont understand any of the material online at all.
the question
y-2x=17
x-y=-8
im confused because when solving for x the number doesn't divide into 17at all so what am i supposed to do? in addition i get really confused when finding the y value as well?
can someone please explain fully and in simple terms how you solve this type of equation?
thank you
