If 2a=8, a=4 (divide both sides by 2)
Then, substitute this value into the second equation to get:
4%2Bb=2
b=-2 (subtract 4 from both sides).
Giving solution set S={4,-2}

First solve for a in the first equation:
2a=8
a=4

Next,substitute a=4 into the second equation:
a+b=2
4+b = 2
b=-2

Solution is (4,-2)
