The answer is 20/3 first you set a variable x and 30x=200 divid both side by 30 and get the final answer
Using the rule for 2x2 matrices,

the determinant for your matrix is
Im assuming that the difference is 78:-
2a + c = 180 ( Note 2a = a +b because we are given that a = b))
c - a = 78 Subtract:-
3a = 102
a = 34
So a=34, b=34 and c = 112 Answer.
