Solve by the elimination method 0.3x - 0.2y equals 4 0.2x 0.3y equals 5 over 23 What is the solution of the system Type an ordered pair. Type an integer or a fraction.?

0.3x - 0.2y = 4 (or you can multiply by 10 in order to work with whole numbers)

0.2x - 0.3y = 5/23

3x - 2y = 40

2x -3y = 50/23

2(3x) - 2(2y)= 2(40)

-3(2x) - (-3)(3y) = (-3)(50/23)

6x - 4y = 80

-6x +9y = -150/23

6x - 6x - 4y + 9y = 80 - 150/23

5y = 1690/23

y = (1690/23)/(5)

y = (1690/23)(1/5)

y = 338/23

2x - 3y = 50/23

2(338/23) - 3y = 50/23

676/23 -3y = 50/23

-3y = -676/23 + 60/23

-3y = -616/23

y = (-616/23)/(-3)

y = (-616/23)(-1/3)

y = 616/69
