3/4 = 6/x....3/4 = 6/8...notice that proportions are nothing but equivalent fractions
x = 8
1) wrote as addition of the additive inverse
2) wrote terms as addition of opposite
3) grouped like terms
4) combined like terms
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

Step-by-step explanation:
A. 3x+4/2 = 9.5
3x + 4/2 = 9.5........criss cross
3x+4= 9.5×2
3x = 19-4
3x = 15
x=5 ..........divide both sides by 3
B. 7+ 2x/3= 5.......criss cross
7+2x = 5 × 3
7 + 2x = 15
2x = 15-7
2x = 8......divide both sides by 2
x = 4
