Question

Amaya used these steps to solve the equation 8x+4=9+4(2x−1). Which choice describes the meaning of her result, 4=5?

Answer 1

Answer: she distributed then subtracted twice to get 4=5. The answer is correct.

Step-by-step explanation:

8x+4=9+4(2x-1). Given

8x+4=9+8x-4 Distributive

-8x = -8x Subtract 8x from each side

4=9-4 Subtract 9-4

4=5 Answer

Answer 2

No value of x can make the equation true.

Step-by-step explanation:

Given : Amaya used these steps to solve the equation  $8x+4=9+4(2x-1)$.

To find : Which choice describes the meaning of her result, 4=5?

Solution :

We solve the equation step by step,

Step 1 - Write the equation,

$8x+4=9+4(2x-1)$

Step 2 - Apply distributive property, $a(b+c)=ab+ac$

$8x+4=9+8x-4$

$8x+4=5+8x$

Step 3- Subtract 8x both side,

$8x+4-8x=5+8x-8x$

$4=5$

Which means no value of x can make the equation true.
