What is the solution to this equation?
x + 20 + 10x = 20 + 9x
o a. x=2
o b. x = 0
o c. x= 10
o d. x= 20

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
