Before jumping into doing this problem, it is important to look at all the information's that have been made available in the question. Based on those given conditions the answer to the problem can be easily deduced.
Let us assume the number of friends Sumalee has = x
Then
2x + 8 = 40
2x = 40 -8
2x = 32
x = 32/2
x = 16
So Sumalee has 16 friends. There are numerous ways to get to the answer that is required to be found. This is the easiest and the shortest method. Hope i helped you.
Answer:
m-a = n
Step-by-step explanation:
a=m-n
Subtract m from each side
a-m = m-n-m
a-m = -n
Multiply each side by -1
-a+m = n
m-a = n
Answer:
The solution to the system of equations be:
Hece, option B is correct.
Step-by-step explanation:
Given the system of equations
Multiply x − 3y = 6 by 2: 2x-6y=12
so
so the system of equations becomes
Solve 8y = -8 for y
Divide both sides by 8
subtract 6 from both sides
Divide both sides by 2
Therefore, the solution to the system of equations be:
Hence, option B is correct.
