The method which is best for solving the system of equations when you remove one variable by adding them is B Elimination
To answer the question, we need to know what system of equations are
<h3>What are system of equations?</h3>
System of equations are pairs of equations that contain two unknowns
<h3>Ways of solving system of equations</h3>
We have different ways of solving systems of equations which include
- Guess and Check
- Elimination
- Graphing and
- Substitution
Since we have the system of equations
3x + 2y = 4
-3x + y = 2
The method which we can use to remove one variable by adding them is the elimination method.
Adding them, we have
3x + 2y = 4
+
-3x + y = 2
3y = 6
y = 6/3
y = 2
So, the method which we can use to remove one variable by adding them is B Elimination

Since the formula for circumference is
2 pi r, you can multiply 28 by pi to get 87.92
Answer: 87.92
250$÷5=50
each people 50
3 sister = 150
2 nephews = 100
spend 10$ to each sister
100$N - 30$spend =70$N
3S= (150$ + 30$ )
= 180$÷3
=60$
2N=70$÷3 =23.33$
