Answer:
21
Step-by-step explanation:
use PEMDAS
multiplication first
120-20×5+1 =
120-100+1=
20+1= 21
Step-by-step explanation:
Example 1:
a+c=b+c then a=b
First let the value of a and b be different (not equal)
a=5
b=7
c=10
a+c=b+c
5+10=7+10
15≠17
Example 2:
Let the value a and b be equal (the same)
a=5
b=5
c=10
a+c=b+c
5+10=5+10
15=15
So when,
a+c and b+c is equal, a and b are <u>always</u><u> </u> equal.
