Evaluate the simultaneous equations 2x + 4y = 13; x + y = 4 by using the Elimination
Method.

Look below

Step-by-step explanation:

Either remove the x or y

Lets do X first

In order to remove the 2 from eqaution A, we need to make the coefficient be the same for the x in the equation B.

We can multiply eqaution B by 2 in order to have the same x coefficient as eqaution A. In addition, we must make the 2 a negative (-2) in order to remove x.

Now that we have the Xs ready for the elimination, we can proceed to answer for y

Now solve for y

Now plug in 2.5 for either equation to find x ( in this case, B to make my life easier)

Which in order to trust the other equation ( for some people to trust the answer for X -_-)

And from there, we conclude that x = 1.5 and y = 2.5

Now, we can get the same result if we eliminated y instead of x

(also this is copy and pasted from x because I am too lazy, get use to it)

In order to remove the 4 from eqaution A, we need to make the coefficient be the same for the y in the equation B.

We can multiply eqaution B by 4 in order to have the same x coefficient as eqaution A. In addition, we must make the 4 a negative (-4) in order to remove x.

Now that we have the Ys ready for the elimination, we can proceed to answer for x

Now solve for x

Afterward, we are then able to do the same thing to find Y as we did previously in the previous section

Was this worth my time? No

Was it worth it? Yes

Why? I did this instead of a buddy's speech, so lol its funny to me lol

∞ this is your sign
