You solve the substitution method to solve a system of equality by expressing one variable in terms of the other using one equation, and then plugging this expression in the other(s).
In this case, the first equation gives us a way to express n in terms of m. So, we can replace every occurrence of n in the second equation with the given formula.
The result is

So, the second equation turned to be an equality, i.e. an equation where both sides are the same.
This implies that the system has infinitely many solutions, because every couple
such that
is a solution to the system, because it satisfies both equations: the first is trivially satisfied, whereas the second is an identity, and as such is satisfied by any value of the variable.

Answer: it is the one your cursor is on
Step-by-step explanation:
I just put it in a calculator and it showed me
39/50= 0.78 times 100= 78
78 is Donovan's score
if maci's score is 10 percentage points higher
78+10=88
x /50 =0.88 times 100= 88
x=44
each question is 2 points: 88-78= 10/2=5
