Answer» (a) z + 1, z – 1, y + 17, y – 17 Addition as 1 is added to z Subtraction as 1 is subtracted from z Addition as 17 is added to y Subtraction as 17 is subtracted from y (b) 17y, y/17, 5z Multiplication as y is multiplied as y is multiplied with 17 Division as y is divided by 17 Multiplication as z is multiplied with 5 Multiplication as z is multiplied with 5 (c) 2y + 17, 2y – 17 Multiplication and addition y is multiplied with 2, and 17 is added to the result (d) 7m, -7m + 3, -7m – 3 Multiplication with 2 and 17 is subtracted from the result Multiplication and subtractions m is multiplied by 7 and 3 is subtracted from the result |
