What is -7n-4=24 lol i hate homework

Montano1993 [528]

It's a simple linear equation in 'n'. There's only one number that 'n' can be
that will make the equation a true statement. That number is called the
'solution' to the equation. Here's one way to find it:

You said that <u> -7n - 4 = 24</u>

Add 4 to each side:    -7n = 28

Multiply each side by -1 : 7n   = -28

Divide each side by 7 :    <em>n      = -4</em>

Homework is the only way for most people to learn stuff.
