3y + 1 = 253y = 25 - 1y = 24 / 3y = 811.
2c + 1 = 192c = 19 - 1c = 18 / 2c = 92.
3u + 8 = 323u = 32 - 8u = 24 / 3u = 87.
3c + 3 = 153c = 15 - 3c = 12 / 4c = 312.
3x + 6 = 153x = 15 - 6x = 9 / 3x = 33.
2u + 7 = 132u = 13 - 7u = 6 / 2u = 38.
3c + 6 = 123c = 12 - 6c = 6 / 2c = 313.
2u + 8 = 102u = 10 - 8u = 2 / 2u = 14.
3y + 6 = 93y = 9 - 6y = 3 / 3y = 19.
3x + 9 = 153x = 15 - 9x = 6 / 3x = 214.
3. x + 7 = 133x = 13 - 7x = 6 / 3x = 25.
2r + 2 = 162r = 16 - 2r = 14 / 2r = 715.
3c + 2 = 293c = 29 - 2c = 27 / 3c = 710.
3x + 8 = 293x = 29 - 8x = 21 / 3x = 7.
