Answer:

x=0

Explanation:

−9x+9(8x+1)=9

Step 1: Simplify both sides of the equation.

−9x+9(8x+1)=9

−9x+(9)(8x)+(9)(1)=9(Distribute)

−9x+72x+9=9

(−9x+72x)+(9)=9(Combine Like Terms)

63x+9=9

63x+9=9

Step 2: Subtract 9 from both sides.

63x+9−9=9−9

63x=0

Step 3: Divide both sides by 63.

63x

63

=

0
