Step-by-step explanation:
I had the question
Donnell practiced for 7 hours while Marcus practices the piano for 4 hours.
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the number of hours piano played by Donnell is D while by Marcus is M.
Then,
Since Donnell practiced the piano 3 hours longer than Marcus.
D = 3 + M ⇒ D - M = 3
And,
Together, Marcus and Donnelly practiced the piano for 11 hours.
D + M = 11
By adding
2D = 14
D = 7
And,
M = 11 - 7 = 4
Hence "Donnell practiced for 7 hours while Marcus practices the piano for 4 hours".

The solution to the equation 42 = 8m + 13m is m = 2.
Here, we have,
To solve the equation 42 = 8m + 13m, you can combine like terms and isolate the variable "m".
Here's how you can do it step by step:
Combine the like terms:
42 = (8 + 13)m
Simplify:
42 = 21m
Divide both sides of the equation by 21 to isolate "m":
42/21 = (21m)/21
Simplify further:
2 = m
Therefore, the solution to the equation 42 = 8m + 13m is m = 2.
