Question

Lixin is thinking of a number. If she multiply the number by 2 and adds 14 to the result, the answer is the same as multiplies the number by 4 and subtracts 8 from the result. Let the number be x, write an equation in terms of x

Answer 1

Answer:

2x + 14 = 4x - 8

14 + 8 = 4x - 2x

22 = 2x

x = 22 ÷ 2

x = 11

Answer 2

2x - 22 = 0 is the equation in terms of x.

Step-by-step explanation:

Let the number = x

She multiply the number by 2 and adds 14.

2x + 14

Also,

She multiplies the number by 4 and subtracts 8 from the result.

4x - 8

According to question,

2x + 14 = 4x - 8

⇒ 4x - 8 - 2x -14 = 0

⇒ 2x - 22 = 0, this is the equation in terms of x.

Hence, 2x - 22 = 0 is the equation in terms of x.
