Answer with Step-by-step explanation:
Amaya used these steps to solve the equation 8x + 4 = 9 + 4 (2x-1).
Which choice describes the meaning of her result, 4=5?
on solving the equation
8x+4=9+4(2x-1)
distributing 4 with both 2x and -1
8x+4=9+8x-4
8x+4=5+8x
subtracting both sides by 8x yields
4=5
She distributed the 4 to the 2x-1, giving her 9+ 8x -4. she subtracted 8x from both sides leaving her with 4=9-4 which is the same as 4=5
