Which of the following ordered pairs represents the solution to the system of equations below? -3x+2y=2 7x-3y=7 a. (2, 4) b. (4, 7) c. (7, 14) d. (8, 13)

-3x + 2y = 2  eq (1)

  7x - 3y = 7    eq (2)

Mutiply eq (1) by 3 and eq (2) by 2:

-9x + 6y = 6

14x - 6y = 14

Add th two new equations:

-9x + 14x = 6 + 14

=> 5x = 20

=> x = 20/5

=> x = 4

Now from eq (1)

-3(4) + 2y = 2

=> 2y = 2 + 12

=> 2y = 14

=> y = 14 / 2

=> y = 7

So the ordered pair is (4,7)

option B. (4,7)

Yes, that is the correct formula. to solve this problem given the number of years, plug in the number of years for t and plug the whole thing into the
