Responses
A x = −3

x = −3
B x = −2x = −2
C x = 2x = 2
D x = 4

Answer 1

To solve the equation, first combine like terms on the left side:

15x + 3x + 19 = -17
18x + 19 = -17

Next, isolate x by subtracting 19 from both sides:

18x + 19 - 19 = -17 - 19
18x = -36

Finally, divide both sides by 18 to solve for x:

(18x)/18 = -36/18
x = -2

Therefore, the solution for x is x = -2. So, the correct answer is B.
