X+20+10x=20+9x
adding like terms
x(10+1)+20=20+9x
11x+20=9x+20
subtracting 9x from both sides
2x+20=20
subtracting 20 from both sides
2x=0
dividing by two for both sides
x=0

Answer:

x = 0

Step-by-step explanation:

x + 20 + 10x = 20 + 9x

combine like terms

20 + 11x = 20 + 9x

-20 from both sides

11x = 9x

-9x from both sides

2x = 0

/2 from both sides

x = 0/2

0/2 = 0

x = 0
