Answer:
[tex]26[/tex]
Step-by-step explanation:
[tex]2n-6[/tex]
Given that:
[tex]n=16[/tex]
To evaluate the expression, we must simply substitute the given value of [tex]n[/tex], which is [tex]16[/tex], for [tex]n[/tex]:
[tex]2(16)-6[/tex]
Multiply:
[tex]32-6[/tex]
Subtract:
[tex]26[/tex]
-
To check your work, simply set the given expression equal to our solution, [tex]26[/tex]:
[tex]2n-6=26[/tex]
Add [tex]6[/tex] to both sides of the equation:
[tex]2n=32[/tex]
Divide both sides of the equation by the coefficient of [tex]n[/tex], which is [tex]2[/tex]:
[tex]n=16[/tex]
Since it matches the given value of [tex]n[/tex], our solution is correct!
