Solve the linear equation and simplify your answer. Express your solution as an integer, a simplified fraction, or a decimal rounded to two decimal places.

n+0.2n+3.9=1.5(n−1)

Respuesta :

Answer:

n = 18

Step-by-step explanation:

given the equation

n + 0.2n + 3.9 = 1.5(n - 1) ← distribute parenthesis

1.2n + 3.9 = 1.5n - 1.5 ( subtract 1.2n from both sides )

3.9 = 0.3n - 1.5 ( add 1.5 to both sides )

5.4 = 0.3n ( divide both sides by 0.3 )

[tex]\frac{5.4}{0.3}[/tex] = n , then

n = 18
