Distribute the 2 into the 2x and -y
Then add “like terms” which are 3x and 4x... 3y and -2y
Which then becomes 7x+y
There are no more “like terms” so that is your final answer

Here is the equation:
Since both decimals are negative, the answer will be positive.
- Negative times Negative = Positive
Divide both sides by -3.9 to leave the variable alone:
r is equal to 4 → r = 4
