Question 7754
{{{ 6(n+2)-n = 24 }}} <---- start here.


{{{ 6n + 12 - n = 24 }}} <--- use distributive property to get rid of parentheses.


{{{ 5n + 12 = 24 }}} <---- combine like terms by subtraction.


{{{ 5n = 12 }}} <---- subtract 12 from both sides so that the 5n term will be alone


{{{ n = 12/5 }}} <---- divide both sides by 5 to finally isolate the n from everything else.
