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

Top one
y=-1.7+11y
x=-1.55+10y
Bottom one
y=-7.14-5x
V(sphere) = 4/3 * π * r³ . Therefore, the volume of a hemisphere formula is as follows: V = V(sphere)/2 , V = 2/3 * π * r³ .
