3b + 2a = 2 and -2 + a = 8
-2 + a = 8 can be rearranged to show a = 8 + 2 = 10 (Effectively 2 has been added to both sides.)
As a = 10, the value for a can now be substituted in the equation 3b + 2a = 2
3b + 2x10 = 2 : 3b + 20 = 2 this can be rearranged to show 3b = 2 - 20 = -18
and dividing both sides by 3 gives b = -6.
