Question

The sum of a number and -35 is 98 find the number

Answer 1

x + (- 35) = 98  

x - 35 = 98  [x will represent the missing number]  Add 35 on both sides

x - 35 + 35 = 98 + 35

x = 133

[proof]

133 - 35 = 98

98 = 98

Answer 2

The correct answer to this question is 133. 133 + (-35) = 98
