Question

2 (n - 1) + 47 = 2 (3n - 1)

Answer 1

$\\ \sf\longmapsto 2(n-1)+47=2(3n-1)$

$\\ \sf\longmapsto 2n-2+47=6n-2$

$\\ \sf\longmapsto 2n+47=6n$

$\\ \sf\longmapsto 4n=47$

$\\ \sf\longmapsto n\approx 12$

Answer 2

Answer:

n = 11.75

Step-by-step explanation:

2(n - 1) + 47 = 2(3n - 1)              Distribute the multiplier

2n - 2 + 47 = 6n - 2                 Combine terms

              47 = 4n                       divide

                n = 11.75
