| 2) Solve the expressions, add: 18V - 15D, 3D - 8V + 13 Answer: 10V - Answer: 12D Answer: 13 SOLUTION 1 : (18V -15D) + (3D -8V + 13) = 18V -15D + 3D -8V + 13 = (18V -8V) + (-15D + 3D) + 13 = (18- 8)V + (-15 + 3)D + 13 = 10V - 12D + 13 |
| 3) Solve the expressions, add: 22W - 16Y, 8Y - 2W + 19 Answer: 20W - Answer: 8Y Answer: 19 SOLUTION 1 : (22W -16Y) + (8Y -2W + 19) = 22W -16Y + 8Y -2W + 19 = (22W -2W) + (-16Y + 8Y) + 19 = (22- 2)W + (-16 + 8)Y + 19 = 20W - 8Y + 19 |
| 4) Solve the expressions, add: 17M - 23H, 9H - 2M + 5 Answer: 15M - Answer: 14H Answer: 5 SOLUTION 1 : (17M -23H) + (9H -2M + 5) = 17M -23H + 9H -2M + 5 = (17M -2M) + (-23H + 9H) + 5 = (17- 2)M + (-23 + 9)H + 5 = 15M - 14H + 5 |
| 5) Solve the expressions, add: 12O - 18P, 7P - 4O + 10 Answer: 8O - Answer: 11P Answer: 10 SOLUTION 1 : (12O -18P) + (7P -4O + 10) = 12O -18P + 7P -4O + 10 = (12O -4O) + (-18P + 7P) + 10 = (12- 4)O + (-18 + 7)P + 10 = 8O - 11P + 10 |
| 6) Solve the expressions, add: 21V - 16B, 6B - 4V + 21 Answer: 17V - Answer: 10B Answer: 21 SOLUTION 1 : (21V -16B) + (6B -4V + 21) = 21V -16B + 6B -4V + 21 = (21V -4V) + (-16B + 6B) + 21 = (21- 4)V + (-16 + 6)B + 21 = 17V - 10B + 21 |
