Question

The sum of 42 and twice a number is 164. find the number

Answer 1

61 should be correct

Answer 2

61

Explanation:

let the number be x then twice the number is 2x, hence

42 + 2x = 164 ( subtract 42 from both sides of the equation )

2x = 122 ( divide both sides by 2 )

x = 61

Hence the number is 61
