2a + 3c = 5 a + 2c =1 There is an ordered pair that is the solution of the system of equations shown. The value of one of the variables in the solution of the system can be obtained by using which of the following substitutions? A 2 (2c - 1) + 3c= 5, because a = 2c - 1. B 2 (1 - 2c) + 3c=5, because a = 1- 2c. C 2a + 3 (a - 1) = 5, because c= a - 1. 2a +3 (1 - a) = 5, becausec=1-a.
