1) 3(a-b)=9
2) 4a=b+2
How do I acheive an ordered pair via the elimination method with this equation??
Thanks much!
Johnny did NOT use the elimination method - he used substitution:
3(a-b)=9
4a=b+2
a - b = 3
4a - b = 2
I'm going to multiply the first equation by -1, then add the two equations:
-a + b = -3
4a - b = 2
3a = -1
a = -1/3
Now substitute a into either equation to find b.
