solve the system using substitution. show all your work and write your
answer as an ordered pair (x, y).

Explanation:

Step1: Substitute $x=5y$ into $x+y=18$

$5y + y = 18$

Step2: Combine like terms

$6y = 18$

Step3: Solve for $y$

$y = \frac{18}{6} = 3$

Step4: Substitute $y=3$ into $x=5y$

$x = 5\times3 = 15$
