Answer:
45 = 45
or
just 45.
Step-by-step explanation:
a = 6 , b = 2
3(6) + 4(2)^3 - 5 = 3(6) + 4(2)^3 - 5 (Given)
18 + 32 - 5 = 18 + 32 - 5 (Solve parenthesis)
45 = 45 (combine like terms)
45 does equal 45 so there is the solution. There is infinite many solutions.

Based on the percentage that passed English and those who passed Mathematics and those who failed and passed both, the total number of students who appeared in the examination are 60 students.
The number of students who passed only in Math are 12 students.
<h3>What number of students sat in the exam?</h3>
This can be found as:
= Total who passed English only + Total who passed Math only + Total who failed both + Total who passed both
Assuming the total is n, the equation becomes:
n = 0.75n - 21 + 0.55n - 21 + 21 + 0.05n
n = 1.35n - 21
21 = 0.35n
n = 21 / 0.35
= 60 students
The number who passed mathematics only is:
= (60 x 55%) - students who passed both
= 33 - 21
= 12 students
