15. MAGIC NUMBERS: Sean is
trying to find two numbers with a
sum of 14 and a difference of 4.
Define two variables, write a
system of equations, and solve
by graphing.
17. Substitution to Solve
x + 3y = -28 and y = -5x

3x + 2y = 16 and x = 3y - 2
19. Substitution to Solve
x – y = 8 and y = -3x
20. Substitution to Solve
y = 5x – 3 and x + 2y = 27
22. GEOMETRY: The perimeter of
a rectangle is 48 inches. The
length is 6 inches greater than

bought 24 baseball cards for $50.
One type of card costs $1 per
card, and the other cost $3 per
card. Define the variables, and
write equations to find the
number of each type of card he
bought. Solve by using
elimination.
