For the first question, "The sum of -4x and 2 is 9", we need to write the equation that represents this statement. Since the phrase "the sum of -4x and 2" means we are adding -4x and 2, the equation can be written as -4x + 2 = 9. Therefore, the correct equation is A) -4x + 2 = 9.
Now let's solve the second problem you mentioned, which is the equation: (1/3)x = 12.
To solve this equation, we need to isolate x. To do that, we can multiply both sides of the equation by the reciprocal of the coefficient of x, which in this case is 3.
(3/1) * (1/3)x = (3/1) * 12
The left side simplifies to:
1x = 36/1
Simplifying the right side:
x = 36
So the correct answer is C) x = 36.
For the second problem, you were indeed correct. Well done!
