5(4n-11) - 3n + 20
To get equivalent expression we remove the parenthesis and combine like terms
We distribute 5 inside the parenthesis 4n - 11
5 times 4n = 20n
5 times -11 = -55
So expression becomes
20n - 55 - 3n + 20
Now we combine like terms
20n and -3n are like terms
20n - 3n is 17n, also -55 + 20 is -35
so expression becomes -17n -35
