Math Problem Statement

Which statement about the ordered pairs (3, −8) and (4, 4) is true for the equation 3x−y4=11?

Responses

(4,  4) is a solution to the equation but not (3, −8). Begin ordered pair 4 comma 4 end orderd pair is a solution to the equation but not Begin ordered pair 3 comma negative 8 end ordered pair .

(3, −8) is a solution to the equation but not (4, 4). Begin ordered pair 3 comma negative 8 end ordered pair is a solution to the equation but not Begin ordered pair 4 comma 4 end ordered pair .

Both ordered pairs are solutions. Both ordered pairs are solutions.

Neither ordered pair is a solution.

Solution

We need to check whether each ordered pair satisfies the given equation:

3xy4=113x - \frac{y}{4} = 11

For the first ordered pair (3,8)(3, -8):

Substitute x=3x = 3 and y=8y = -8 into the equation:

3(3)84=113(3) - \frac{-8}{4} = 11 9+2=119 + 2 = 11 11=1111 = 11

Since the equation holds true, (3,8)(3, -8) is a solution.

For the second ordered pair (4,4)(4, 4):

Substitute x=4x = 4 and y=4y = 4 into the equation:

3(4)44=113(4) - \frac{4}{4} = 11 121=1112 - 1 = 11 11=1111 = 11

Since this equation also holds true, (4,4)(4, 4) is a solution.

Conclusion:

Both ordered pairs are solutions. Thus, the correct response is:

Both ordered pairs are solutions.
