1) 2x + 3 + 4x = 6x + 3
2) 2x - 3 - 4x = -2x - 3
3) 2x - 3 + 4x = 6x - 3
4) 3m + 1 + 2m = 5m + 1
5) 3m - 1 - 2m = m - 1
6) 3m - 1 + 2m = 5m - 11) 2x + 1 + 2y
2) a + 3 - 3b
3) 2x - 1 - 2y
4) a - 3 + 3b
5) b + c - a + 2d1) 3a + 3 + 3a = 6a + 3
2) 2m - 2 + 2m = 4m - 2
3) 5m + 15n + 4m - 2n = 9m + 13n
4) 3x + 6y + 8x - 4y = 11x + 2y
5) 14x + 21y - 3x - 2y = 11x + 19y
6) 30c + 15d - 6c - 12d = 24c + 3d
7) 10c + 8d - 8c - 10d = 2c - 2d1) 4 - 3(1,710 + 3) = 4 - 3(17 + 3) = 4 - 60 = -56
2) 5 - 7(0,03100 + 4) = 5 - 7(3 + 4) = 5 - 49 = -44
3) 25 + 1/4(2,45 - 3) = 10 + 1/4(12 - 3) = 10 + 1/49 = 10 + 2.25 = 12.25
4) 630 + 1/5(1.530 - 3) = 180 + 1/5(45 - 3) = 180 + 1/542 = 180 + 8.4 = 188.4
