x = 8

Group of answer choices

(8, 15)

(0, 8)

(8, 47)

(0, 7)

1 answer

To solve the system of equations using the substitution method, we start with the given equations:

  1. \( y = 5x + 7 \)
  2. \( x = 8 \)

Now, we can substitute \( x = 8 \) into the first equation to find \( y \):

\[ y = 5(8) + 7 \] \[ y = 40 + 7 \] \[ y = 47 \]

So, the ordered pair is \( (8, 47) \).

Thus, the correct answer is:

(8, 47)
