The answer is 21 because 189 divided by 9 is 21
3x + 1y = ¹/₃ ⇒ 9x + 3y = 1
2x - 3y = 2²/₃ ⇒ 2x - 3y = 2²/₃
11x = 3²/₃
11 11
x = ¹/₃
3x + y = ¹/₃
3(¹/₃) + y = ¹/₃
1 + y = ¹/₃
- 1 - 1
y = ⁻²/₃
(x, y) = (¹/₃, ⁻²/₃)

15.5 15.5 x 2 = 31. hope this helps
3x+8+4x=-8x+48–104x–40
7x+8=-112x+8
-7x -7x
8=-119x+8
-8 -8
0=-119x
0=x
