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

A year is about 52 weeks.
So in a week, 40 ounces is gained.
In 52 weeks, you should multiply 40 by 52.
40 x 52 = 2080 ounces.
There are 16 ounces to a pound
2080 divide by 16 = 130 pounds.
Answer:
do 3 dived by 2 they the awnser times seven then add 105 then multiply 60 then carry the 3 then add 10 and 6 then add 16 to the awnser and boom!
Step-by-step explanation:
Answer: A and D are the correct statements.
1. In ΔBRS and ΔBDC
∠R=∠D and ∠S=∠C [∵ corresponding angles]
So by AA similarity criteria ,
△BCD is similar to △BSR.
2. As RS is parallel to DS then by basic proportionality theorem,
⇒ B is not true.
3. As we can see BC is greater than BS ,so it cannot possible.
If and
where BS=6 then .
4. As RS is parallel to DS then by basic proportionality theorem,
⇒BR×SC=RD×BS.
5. From 4 its not true that BR/RS = BS/SC.
9.7 is a rational number and a real number.
