C. 2x + 6
Step-by-step explanation:
After doing synthetic division (see attached), you get 2, 6, and 0, corresponding to the answer 2x + 6.
Substitute the given value of y into the equation y=7x+15
Move the variable to the left-hand side and change its sign
Collect like terms
Divide both sides of the equation by -5
Substitute the given value of x into the equation y=2x
Solve the equation for y
The possible solution of the system is the ordered pair (x,y)
