I thought of doing -2x=8-y
that can work, but things will get complicated soon.
16+4x=2(8+2x)
I see... I will use the way u told me than
yes, simplify 2(8+2x)
16+4x=16+4x
O.O IMPOSSIBLE
correct. now think logically, when is that true
not impossible its like 0=0
S0 infinite number of solutions
you take any value of x or y 16+4x will always be = 16+4x so, yes, infinite solutions :)
yay! Thanks so much
Note how one of the given equations is a multiple of the other given equation. That's all the info you need to decide "infinitely many solutions."
I see, Thanks :)
