Solving Equations Using Substitution

Solve the following systems of equations using substitution:

y = 8

y = -4x + 4

• (8, -1)

• (-28, 8)

• (-1, 8)

• (8, -28)

Solve the following systems of equations using substitution:

• (6, 6)

• (6, 9)

• (9, 6)

• (9, 9)

4x - 5y = 21

x - 3y = 7

• (4, -1)

• (-4, -1)

• (-3, 2)

• (1, -3)

Solve for x and y using the substitution method. 5x + 3y = 7 y = 4

• (4,1)

• (4,-1)

• (1,4)

• (-1,4)

• (1, 2)

• (4, 1)

• (2, -1)

• No Solution
