Answer 1

c

Explanation:

got it right on the test

Answer 2

9514 1404 393

Answer:

(c) (4, 3)

Explanation:

The next step in the solution of System B is to divide by 15 1/2. This will result in the equation ...

x = 4

The only answer choice that has x = 4 is the ordered pair (4, 3). That ordered pair is the solution to the system.

__

(15 1/2)x = 62 ⇒ (31/2)x = 124/2 ⇒ x = (124/2)/(31/2) = 124/31 = 4
