4a is both 6-b and 2-b. So 6-b = 2-b
-------------------------------------------------------
Another way to say it is...
4a=6-b ... Start with the first equation.
2-b=6-b ... Replace '4a' with '2-b' (since 4a = 2-b)
-------------------------------------------------------
Now solve for b. Then use the solution to find 'a'.
