Answer:

(x, y) = (8, 5)

Explanation:

I like to use a graphing calculator with weird equations like these. (See the attached.)

_____

If you want to solve by hand, you can eliminate fractions, then use your favorite method: substitution, elimination, Cramer's rule, graphing, matrix methods, guess and check, whatever.

Multiply the first equation by 2.

... 6y = 3x +6

This has a factor of 3 that can be removed, and it can be put into standard form by subtracting y and the constant.

... x - 2y = -2

Multiply the second equation by 4.

... 4y - x = 12

You can add these equation to eliminate x.

... (x -2y) +(4y -x) = (-2) +(12)

... 2y = 10 . . . . . . simplify

... y = 5 . . . . . . . . divide by the coefficient of y

Now you can use either equation to find x.

... x - 2·5 = -2

... x = 10 -2 = 8

Then the solution is (x, y) = (8, 5).
