1). 9 а + 13 а = a * (9 + 13) = a * 22 = 22a;

2). 18 х - 4 х = х * (18 - 4) = х * 14 = 14 х;

3). 34b + b = b * (34 + 1) = b * 35 = 35b;

4). 43a - a = a * (43 - 1) = a * 42 = 42a;

5). 8x + 16x + 19x = x * (8 + 16 + 19) = x * 43 = 43x;

6). 53m + 12m - 36m = m * (53 + 12 + 36) = m * 101 = 101m;

7). 14c + 17c + 9 = c * (14 + 17 + 9) = c * 40 = 40c;

8). 69p - 13p + 37 = p * (69 - 13 + 37) = p * 93 = 93p;

9). 14a - 8a + 45a + a = a * (14 - 8 + 45 + 1) = a * 52 = 52a.
