The number. Find the nume.

Eight times a number plus 3 times

the number is the same as 9 more

than 12 times the number. Find the

number.

Answer: 8x+3x=12x+9

The number is - 9.

Step-by-step explanation: Combine like terms.

11x=12x+9

Subtract 12x from the other side. 11x-12x = - 1x

-1x+9

Divide by - 1 to isolate x.

-1/-1 cancels out.

9/-1 = - 9

x=-9

Plug in - 9 to check your answer if you want to double check.
