So you first write the numbers into an equation:
(3x + 2) = 47
(You can remove the parentheses if you'd like.)
So first off, you'd want to isolate 'x' since that's what you're trying to figure out. In order to do that, you must subtract 2 from both sides.
This means you would do: 2 - 2 (which cancels out)
and then you would do 47 - 2, which equals 45.
After that, you should have 3x = 45
Now, divide 3 from both sides.
3x ÷ 3 (cancels out)
45 ÷ 3, which equals 15.
So you're answer is 15.
x = 15
