Solve the system of equations using the addition method: x + 3y = -1
2x + 3y = -5
A) $x = - 3 , y = \frac { 2 } { 3 }$
B) $x = 1 , y = \frac { - 2 } { 3 }$
C) $x = - 4 , y = 1$
D) $x = - 2 , y = - 1$

Question

Quizplus · Accepted Answer

Subtract the first equation from the second to eliminate y: (2x + 3y) - (x + 3y) = -5 - (-1), resulting in x = -4. Substitute x = -4 into the first equation to find y: -4 + 3y = -1, solving gives y = 1.
