Question

A number is doubled and the result is increased by 8. If the final result is 36. What is the number?​

Answer 1

14

Explanation:

This question can be expressed as the following linear equation:

2x+8=36, where x is our unknown number.

From here,

2x+8=36

2x=28 (-8 both sides)

x=14 (/2 both sides)

Therefore the number is 14

Answer 2

Let the number be represented by “x.”
Let’s write the equation:
Doubled=2
Increased=+
Final result= equal

2x + 8 =36
Subtract 8 to both sides to get 2x alone:
2x = 28
Divide both sides by 2:
x = 14
The number is 14, that’s the answer.
