Multiply the term in parentheses by its coefficient:
[tex]4(6 + 2n) = 4 * 6 + 4 * 2n = 24 + 8n[/tex]
[tex]4 - (24 + 8n) = -28[/tex]
[tex]4 - 24 - 8n = -28[/tex]
Combine like terms:
[tex]-20 - 8n = -28[/tex]
Add 20 to both sides:
[tex]-8n = -8[/tex]
Divide both sides by -8 to get n by itself:
[tex]n = 1[/tex]
The value of n is 1.
