First, solve the parenthesis by multiplying the numbers in and out of them:
2+6x-12=12x-6
Next, put them in order so you can solve the equation:
2-12+6=-6x+12x
Next solve:
-4=6x
So x is:
-6/4
So C is the correct answer,
Hopefully, this helps you find the answer! If it doesn't, tell me in the space below and I'll solve it completely

Answer:
Thr answer will be -9
Divide each term by -7 and simplify
Basically it's telling you what equation to use for the specific value of g(x). If x is g(2) then you would use the third equation. 2x - 5. so 2(2)-5= -1
Answer:
[tex]3x + 8y = -20[tex]
[tex]5x - y = -19[tex]
[tex]3x + 8y = -20[tex]
[tex]40x - 8y = -152[tex] (multiply both sides by 8)
Add the two equations together.
[tex](3x + 8y) + (40x - 8y) = -20 + (-152)[tex]
Which makes it
[tex]43x = -172[tex]
Then divide 43 by both sides.
[tex]x = -4[tex]
Then get [tex]y[tex] by substituting [tex]x[tex]
[tex]5 * (-4) - y = -19[tex]
And solve the equation.
[tex]5 * (-4) - y = -19[tex]
[tex]5 * (-4) - (-19) = y[tex]
[tex]-20 + 19 = y[tex]
[tex]y = -1[tex]
So the answer is:
[tex]x = -4 , y = -1[tex]
