Answer: One solution (1 1/6)
Ac - ab = 2
Factor out a
a(c-b) = 2
Then divide the expression by c-b to solve for a.
Do this on both sides.
a(c-b)/(c-b) = 2/(c-b)
a = 2/c-b
The solution is a = 2/c-b.

Answer:
5
Step-by-step explanation:
Add the latter two equations and you get ...
(a +b) +(a -b) = (7) +(3)
2a = 10 . . . . . . . . . . . . . . . simplify
a = 5 . . . . . . . divide by 2
