Question

The ordered pair (4,3) satisfies which of the following

equations:
a. 2x−4y=−6
b. 2x+2y=12
c. 2x+4y=17
d. 2x−y=5

Answer 1

Answer: d. 2x - y = 5

Explanation:

Replace x with 4 and replace y with 3 into each of the equations to see which is a TRUE statement.

a. 2x - 4y = -6

2(4) - 4(3) = -6

8 - 12 = -6

-4 = -6

FALSE

b. 2x + 2y = 12

2(4) + 2(3) = 12

8 + 6 = 12

14 = 12

FALSE

c. 2x + 4y = 17

2(4) + 4(3) = 17

8 + 12 = 17

20 = 17

FALSE

d. 2x - y = 5

2(4) - (3) = 5

8 - 3 = 5

5 = 5

TRUE
