Question

What is the value of the x variable in the solution to the following system of equations?

2x − y = 6
4x − 2y = 12

0

4

x can be any number as there are infinitely many solutions to the system.

There is no x value as there is no solution to the system.

Answer 1

Multiple the entire first equation by 2 and what do you get?

Answer 2

You can either use elimination or subsitution. What method are u suppossed to use?

Answer 3

elemination

Answer 4

Alrighty so I will explain the concept

Answer 5

In order to eliminate a variable they must have the same coefficient in front

Answer 6

So lets eliminate the y

Answer 7

Are the coeeficients in front of both y's the same?

Answer 8

Are u there? lets eliminate the x since it may be easier to understand

Answer 9

So do both x's have he same coefficient?

Answer 10

This is a harder one since both these equations are really one

Answer 11

4x-2y=12
4x-12=2y
2x-6=y
Or it can be written as 2x-y =6

Answer 12

So in essence they are the same equation so there are an infinitely amount of solution where both of these equations meet since they are the same line!!

Answer 13

Did you get that?
