Answer:
[tex]n = 126[/tex]
Step-by-step explanation:
First let's model this into an equation.
Twice a number is [tex]2n[/tex], and that divided by 6 is [tex]\frac{2n}{6}[/tex]. That's equal to 42, so we have [tex]\frac{2n}{6} = 42[/tex].
Now we can simplify this equation by isolating n on one side of the equation.
Multiply both sides by 6:
[tex]\frac{2n}{6} \cdot 6 = 42\cdot 6\\\\2n = 252[/tex]
Divide both sides by 2:
[tex]2n \div 2 = 252\div 2\\\\n = 126[/tex]
Hope this helped!
