Final answer:
To solve the equation x-0.1x=54 for x, combine like terms and isolate x by dividing both sides of the equation by 0.9. The value of x that satisfies the equation is 60.
Step-by-step explanation:
To solve the equation x-0.1x=54 for x, we can combine like terms: 0.9x=54. Then, we isolate x by dividing both sides of the equation by 0.9: x=54/0.9=60.
Therefore, the value of x that satisfies the equation is 60.
