Solve the system of equations and choose the correct ordered pair. 3x-4y=26 2x+8y=-36 a.(2,-5) b.(2,5) c.(6,2) d.(6,-2)

3x-4y=26

2x+8y=-36

We will solve this system with gaus algorithm

We multiply first equation with number 2 and we get

6x-8y=52 => we add second equation to this and we get

8x=16 => x=2 => we replace x=2 in first equation and we get

3*2-4y=26 => 6-4y=26 => -4y=20 => y=-5

The correct answer is A.

Good luck!!!

So for this, I will be doing the elimination method. Firstly, multiply both sides of the first equation by 2:

Next, add the two equations together to get . From here you can solve for x.

For this equation, just divide both sides by 8 and your first answer will be

Now that we have the value of x, substitute it into either equation to solve for y:

In short, the solution is (2,-5), or A.

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
