Solving Systems of Equations by Substitution

Solve:

x = -3y - 17

2x + 3y = -7

• (1, -20)

• (10, 0)

• (-5, -2)

• (10 , -9)

Solve the system of equations.

y = -5x

x + 3y = 28

• (-6, 30)

• (-2, 10)

• (-2, 39)

• (-6, 10)

y = -6x + 5

-2x + y = 5

• (-3, -6)

• (0, 3)

• (0, 5)

• (-3, 5)

Solve:
y = -1x - 5
4x - 8y = 4

• (-3, -2)
• (5, -7)
• (3, 9)
• (-5, 4)

y = 8x + 9

2x + 6y = 8

• (-2, -1)

• (-1, 0)

• (-1, 1)

• (3, 1)

4x + 2y = 12

y = 3x - 14

• (4, -4)

• (4, 4)

• (-2, -2)

• (4, -2)

Solve the following systems of equations using substitution:

2y + x = -15

x = 3y

• (-3, -9)

• (-9, -3)

• (-3, 9)
