Yo has to distribute and add like terms
distributeiv propoerty
a(b+c)=ab+ac aka
a(b-c)=ab-ac
5(4n-11)-3n+20=17n-35
distribuet
5*4n=20n
5*11=55
20n-55-3n+20=17n-35
move like terms together
20n-3n+20-55=17n-35
20-3=17
20-55=35
17n-35=17n-35
true
Hi there!
quarter:18
<u><em>1.Find common denominator in 4 and 1/2:</em></u>

<u><em>2.Convert 4 2/4 into mixed number:</em></u>
<u><em /></u>
