Question

Chloe is thinking of a number. When seven more than this number is doubled, the result is 46. Let n be the number Chloe is thinking of. Set up and solve an equation to find the value of n.

Answer 1

Answer: 16

Explanation:

Assume that this number is x:

When seven more than this number is doubled, the result is 46. In formula form that would be:

2 * (7 + n) = 46

Solving this formula:

2 * ( 7 + n) = 46

7 + n = 46/2

n = 46/2 - 7

n = 16
