Answer:
j = 1
Step-by-step explanation:
4j + 14 = 18j
subtract 4j from both sides
14 = 14j

j = 1
So first, you want to open the parenthesis here.
So, to do that, first look at the symbol before the parenthesis.
In this case it's a -.
So when it's a -, reverse the symbol inside the parenthesis. (This is because if you don't you're subtracting 2x and then adding 8, when really you're subtracting both 2x and 8.)
So,
9x - 2x - 8
Or simplified,
7x - 8
Multiplication and division are inverse operations.
If you start with a number and divide it and multiply it by the same number (not zero), you get the original number back.
Since you want to undo a division by 7, you must multiply by 7.
Answer: A. Multiplying by 7
Answer:
