Answer: 6
Step-by-step explanation: okay. Here we go. This will be long.
You have to use the inverse operation. That means use the opposite operation. For example, the opposite operation of addition is subtraction. So let’s ignore the 3x for now. That means the equation is +2=20. The inverse operation of addition is subtraction. So we subtract 2 from 20. That equals 18. Then we subtract 2 from 2. That equals 0. Now our equation is =18. Now remember 3x? You bring that back in. So our equation is 3x=18. See what I did? I simplified the equation. 3x means “3 times x” because x is a variable. And the opposite of times (multiplication) is division. So you divide 3 from 18. That equals 6. And we divide 3 from 3x. That equals 1x. Ax is basically the same thing as x. So now what doe we have left? X= 6. Your answer is 6.
Answer:
x= 19/4
Step-by-step explanation:
Well, you don't have any options.
But a mixed number for 12.16 would be 12 4/25. Hope it helps! :)
Since all of these numbers have the same variable they can all be added up to get a sum of 10a which is its simplified form.
Y=3x
