Answer: 56 purple marbles.
Step-by-step explanation:
Let be "p" the number of purple marbles in the bag and "w" the number of white marbles in the bag.
You can set up the following System of equations:

You can use the Substitution method to solve the System of equations. The steps are shown below:
1. You need to substitute the second equation into the first equation:

2. Now you must solve for "w":

3. Substitute the value of "w" into second original equation and then evaluate in order to find the value "p":

Answer:
-3.4p + 3p + 4
Step-by-step explanation:
Solve the parenthesis with the minus sign in front of it. Basically, inverse all of the operations within the parenthesis.
The -3q will become a 3q and the -4 will become a 4.
So now with the positive 3q and 4, you will just add those to the -3.4p
Therefore, the answer is -3.4p + 3p + 4
