n =
a. 7
b. 5.6
c. 8.3
d. 6.9
The question is incomplete, as it does not provide any information or context to determine the value of n. Therefore, it is not possible to determine the value of n from the given options.
n/5 + 0.6=2
- 0.6 -0.6
5.n = 1.4 . 5
5
n=
To solve the equation, we will isolate n.
n/5 + 0.6 = 2
Subtract 0.6 from both sides:
n/5 = 2 - 0.6
n/5 = 1.4
Multiply both sides by 5:
5(n/5) = 5(1.4)
n = 7
Therefore, the value of n is 7.
Why is he multiplying by 4?
a. To eliminate the expression
b. To eliminate the variable
c. To eliminate the constant
To eliminate the coefficient
The correct answer is b. To eliminate the variable.
Multiplying by 5 on both sides of the equation helps cancel out the coefficient of n on the left side, leaving us with n by itself. This process, known as "eliminating the variable," is done to solve for the value of the variable in the equation.

Apologies for the confusion caused.
To clarify, we were multiplying both sides of the equation by 5 in order to get rid of the coefficient of 1/5 that is multiplied on the left side of the equation next to n. By multiplying both sides by the reciprocal of 1/5, which is 5/1 or simply 5, the left side simplifies to just n. This allows us to isolate the variable and solve for its value.
