Answer:
[tex]n=\frac{6}{23}[/tex]
Step-by-step explanation:
We need to solve for n.
Equation given is [tex]12n+34n=12[/tex]
We can add the values with n in the left side of the equation:
[tex](12+34)n=12[/tex]
[tex]46n=12[/tex]
Then we can divide both sides by 46.
[tex]\frac{46n}{46} =\frac{12}{46}[/tex]
[tex]n=\frac{12}{46}[/tex]
Now we can simplify the fraction by dividing numerator and denominator by 2.
[tex]n=\frac{6}{23}[/tex]
