What is the y- value of the solution to the linear system below?

the last option is the correct answer.

Step-by-step explanation:

The given system of equations is expressed as

y = - 3x - 12- - - - - - - - - - - - -1

y = 3x + 24- - - - - - - -- - - - - - -2

We would apply the method of elimination. Since x has the same coefficient and the sign is opposite, we would eliminate x by adding equation 1 to equation 2. It becomes

y + y = - 3x + 3x - 12 + 24

2y = 12

Dividing the left hand side and the right hand side of the equation by 2, it becomes

2y/2 = 12/2

y = 6
