Answer:

Explanation:

So first you can set up your linear system to the following:

{

2

x

4

y

=

3

2

x

5

y

=

3

Do this because it is visually easier to simplify the next couple steps.

For the simplification part, I will be using the elimination method on the

x

variables so that we can obtain a

y

variable answer.

Multiply the top equation in the linear system by

1

1

(

2

x

4

y

=

3

)

2

x

5

y

=

3

You should get the following when simplified:

{

2

x

+

4

y

=

3

2

x

5

y

=

3

Next, add the equations together going vertically making sure to add only to the corresponding term.

The

x

values and the numerical values should be equal to

0

when this is done correctly and you should be left with the following:

y

=

0

Then simplify by dividing the

1

coefficient from

y

:

y

=

0

Then you plug the

y

value back into one of the original equations:

2

x

4

(

0

)

=

3

Then simplify:

2

x

=

3

Divide the

2

coefficient from the

x

and you should be just left with

x

=

3

2

=

1.5

Finally, you plug them into a coordinate point that indicates when the two equations intersect:

(

1.5

,

0

)
