To solve the system of equations given:
- \( y = 15 \)
- \( x = 17 - 2y \)
First, substitute the value of \( y \) into the second equation.
Substituting \( y = 15 \) into \( x = 17 - 2y \):
\[ x = 17 - 2(15) \] \[ x = 17 - 30 \] \[ x = -13 \]
Now, we have found the values of \( x \) and \( y \):
- \( x = -13 \)
- \( y = 15 \)
Thus, the solution to the system of equations is:
\((-13, 15)\)
