We can check by subbing in the values.
7x + 2y = -7
(7,9).....x = 7 and y = 9
now we sub
7(7) + 2(9) = -7
49 + 18 = -7
67 = -7 (incorrect)....therefore, (7,9) is NOT a solution for this equation
X = sonias dvds
37 = 4x - 3
+3 +3
40 = 4x
10 = x
<span>sonia has 10 dvds</span>
This is the correct answers
