Help please, show steps<br>3n/7-1=1/8
goldfiish [28.3K]

Given:

\frac{3n}{7}-1=\frac{1}{8}

First, let's move the -1 to the right side. When we add 1 + \frac{1}{8}, we get \frac{9}{8}.

\frac{3n}{7}=\frac{9}{8}

Now we can cross multiply, multiply (3n)(8) and (7)(9)

(3n)(8)=(7)(9)

Simplify the left side.

24n = (7)(9)

Simplify the right side.

24n=63

Divide both sides by 24 to isolate n.

\frac{24n}{24}=\frac{63}{24}

Simplify.

n=\frac{21}{8}
