Question

3(n+1)=5.4 Solve for n

Answer 1

Answer:

n =0.8

Step-by-step explanation:

$3(n+1)=5.4$

Expand ; 3(n+1)

$3(n+1) =3n +3\\\\3n+3 =5.4$

Collect like terms and simplify

$3n =5.4-3\\3n=2.4$

Divide both sides of the equation by 3

$\frac{3n}{3} = \frac{2.4}{3} \\\\n = 0.8$

Answer 2

Answer:

The value of n is 0.8 .

Step-by-step explanation:

First, you have to expand to get rid of brackets :

$3(n + 1) = 5.4$

$3n + 3 = 5.4$

Next, you have to subtract 3 on both sides to remove 3 at the left side :

$3n + 3 - 3 = 5.4 - 3$

$3n = 2.4$

Lastly, you have to divide 3 on both sides :

$3n \div 3 = 2.4 \div 3$

$n = 0.8$
