a + b = 60
a - b = 6
adding equations ... 2 a = 66 (b's cancel)
solve for a , then find b
Vivian's technique works
... but only in a case like this
a - b = 6

x + y = 60
x - y = 6
x = 60 - y
60 - y - y = 6
-2y = -54
y = 27
x + 27 = 60
x = 33
x - y = 6
x = 60 - y
60 - y - y = 6
-2y = -54
y = 27
x + 27 = 60
x = 33
