Substitution Final Answer

Is the student finished solving?

• No, you need to find what y equals.

• No, you can't have negative answers.

• There is no solution.

Solve:
x = -3y - 17
2x + 3y = -7

If you partially solve the system and got y=-9, find the value of x.

Solve the system of equations.

• (10, 3)

• (6, 3)

• (15, 3)

Solve the system of equations.

• (11, 21)

• (3, 11)

• (11, -67)

Solve the system of equations using substitution:
-4x + 4y = 8
y = -2x - 10

If you worked through solving the system and got x = -4, find the value of y.

Solve the system of equations.

• (-7, 8)

• (-7, -6)

• (8, -7)

Solve the system:
x + 6y = 17
x - 3y = 8

If you already solved the system of equations for y and got x = 11, find the value of y.
