Answer:
No solution for the given algebraic expression.
Step-by-step explanation:
To solve the algebraic equation we must isolating the variable or rewriting the equation so that the one expression is only the variable with the coefficient 1.
Solve: 
Now put every terms that contains variables on one side of the equation and those terms on the other side which does not contains the variable.

Combine like terms:

which is not true.
therefore, the given expression have NO SOLUTION.

Looking at number 4, you first have to look at the information that you have:
On tuesday he practiced for 1 5/6 hrs
Monday he practiced for 7/10 hrs
He is supposed to practice for 1 1/4 hr.
You could write questions like:
How much more did Marco practice on Tuesday than he is supposed to practice?
This works because it does indeed involve subtraction, you would be subtracting the amount that he should have practiced from the amount of time that he did practice.
