Question

Solve the system of equations by the substitution method.



Choose one answer.
a. (-8, 0)
b. (0, -8)
c. infinite number of solutions
d. no solution

Answer 1

-4x - 12y = -8
-4x = 12y - 8
x = -3y + 2
Substitute this value of x into the second equation and we get,
6(-3y+2) + 18y = 0
-18y + 12 + 18y = 0
12 = 0
This is a false statement, therefore no solution.

Answer 2

no solution
