Answer:
B) x=0
Step-by-step explanation:
x +20+ 10x= 9x +20
1st step: simplify the left side by combining like terms
10x+x=11x
2nd) 11x+ 20= 9x +20
Next, you subtract 11 and 9 which is equal to 2.
2x+20=20
Now, the 20 cancels out the other twenty so your left with 2x which is not an answer, therefore the only other number is 0 to be possible.
Check: 0+20+0=20 (first expression)
0x9=0 0+20= 20 (2nd expression)
20 = 20 so this is CORRECT!!!!!!!!
