Question

Paul was thinking of a number. Paul doubles it and adds 8.7 to get an answer of 23.4. Form an equation with
x
from the information.

Answer 1

equation is 2x + 8.7 = 23.4 or x=7.35

Explanation:-

Let the number be x

ATQ,

1.Paul doubles the number

so, it becomes 2x

2.Paul adds 8.7 to the number

so, it becomes 2x + 8.7

3. to get an answer of 23.4

so, it becomes 2x + 8.7 = 23.4

or,

2x=23.4-8.7

or,

2x=14.7

or,

x=7.35

Hence, the final equation is 2x + 8.7 = 23.4 or x = 7.35
