What is the solution to the system of equations?

(5, 12)

Step-by-step explanation:

Start with:

3x + 2y = 39

5x -    y  = 13

We'll use elimination by addition/subtraction here.  Multiply the 2nd equation by 2 to obtain -2y, which cancels out the +2y in the first equation:

3x + 2y = 39

10x  -2y  = 26

13x          = 65

Dividing both sides by 13, we get x = 5.

Subbing 5 for x in the 2nd equation, we get 5(5) - y = 13.

Then 25 - y = 13, and      12 - y = 0.  Finally, y = 12.

The solution is (5, 12).

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
