Answer:
Options: A, B, and C correctly solve for x.
Step-by-step explanation:
A).
= 
Multiplying both sides by 2 gives;
5x = 15
x = 15 ÷ 5 = 3
∴ This option correctly solve for x.
B).
x +
= 7
x = 7 -
= 
∴ This option correctly solve for x.
C).
x + 3 = 
x = 
But the option give x as 5/6 hence this option does not correctly solve for x.
D).
5x = 11/2
x = 11/2 ÷ 5 = 11/2 × 1/5 = 11/10
But the option gives x as 10/11 so it does not correctly solve for x.

Step-by-step explanation:
Answer:
A) 
Step-by-step explanation:
An equation is a function of
when
is the independent variable, that is:
(1)
Where
is the dependent variable.
According to this,
does not represent a function of
, since the independent variable is a function of
, that is,
. Therefore, the correct answer is A.
