Answer: A
Step-by-step explanation:
Step-by-step explanation:
2 x 2 + x - 4 = 0
4 + x - 4 = 0
<u>+</u><u>4</u> <u>+4</u>
8 0
<u>8</u> + x = <u>0</u>
8 8
x = 0
For the - 4 + 4 part, it cancels out because it's 0 and for the 8 divided by 8 part, it cancels out too. x is 0 because 0 divided by 8 is 0.
