Mary had 17 candies. For Halloween, she got 13 more candies. How many candies does she have in total?
Answer:
<u>(a) x = 2</u>
Step-by-step explanation:
x - 12 = -8x + 6
First, move all the like terms to one side of the equation. We will move all the x's to the left, and the rest to the right in this equation. (Don't forget to pay attention to the signs of the numbers as you move them over the equal sign.)
x - 12 + 8x = 6
x + 8x = 6 + 12
9x = 18
Next, solve for x by isolating it to one side of the equation. Here, we'll have to divide 18 by 9 (do the opposite of what 9 is doing with x; instead of multiplying it with 18 like it currently is with x, divide 18 by it.)
x =
x = 2
Therefore, your answer is (a), since x = 2.

Answer:
5.833
Step-by-step explanation:
the answer choices don't make sense but I can help u with solving the equation it's x = 1
- 3x-12=-9 , minus 12 on both sides
- 3x = 3 , divide 3 on both sides
- x = 1
now that u know this go through your answer choices and solve their equation and see which one produces x = 1 and that'll be the answer!!
