Yes, now substitute A = -1 into one of the equations to get B
Okay I have these
A+B = 5
4A+ -2/3B = -8
I have a rough idea of what the answer is and my answers are no where near it; this is what I have
Times A+B = 5 by 2
Times 4A + -2/3B = -8 by 3
2A + 2B = 10
12A + -2B = -24
14A = -14
A = -14/14 = -1
is this correct so far?
