hmm this is what ied do a+2b=2 this means a = 2b plug this into second and get 22b+7b=13 clean up and get 5b=15 then b=3 can u do the rest?

okay 2b+7b=13 and 5b=15=3 so that mean that the pair are (5b=15, 3) right?

Goten77 showed that b = 3 a +7b = 13 a +7(3) = 13 ... plug in b = 3 a + 21 = 13 a = 13  21 a = 8  or a+ 2b = 2 a+ 2(3) = 2 a + 6 = 2 a = 2  6 a = 8 So either way, we get a = 8
