-4(2+8) = (-4x2)+(-4xn)
-8-32 = (-8) + (-4n)
-40 = - 8 - 4n
-32 = -4n
8 = n
hope this helped!
First you'd have to switch sides with the equation. After multiply what's inside the first two sets of parenthesis.
-4 ( 2 + 8 ) = ( -4 × 2 ) + ( -4 × n )
( -4 × 2 ) + ( -4 × n ) = -4 ( 2 + 8 )
-8 - 4n = -8 - 32
-8 - 4n = -40
After that you'd add 8 to both sides to make the equation simpler. Or in other words, to simplify. After you add -8 and 8, you should be left with -4n.
-8 + 8 - 4n = -40 + 8
-4n = -32
Finally, you need to divide both sides by -4 to get n on its own.
-4n = -32
[tex] \displaystyle\frac{-4n}{-4} = \frac{-32}{-4} [/tex]
n = 8
The equation can no longer be simplified, so this is our final answer.
n = 8
