Answer:
x=1
Step-by-step explanation:
3x(4+5)=27, we can combine like terms and we have
3x * 9 = 27 , this is another way to write 3x(4+5)=27
27x = 27, this is another way to write 3x(4+5)=27
x= 1, this is another way to write 3x(4+5)=27
12x+15x=27 or
27x=27
or x=1
20 people will ride each bus
60 people, and 3 buses
you would divide 3 by 60
65
128-63=65
