Q. Sixty more than nine times a number is the same as two less than ten times the number. What is the number?
Set Up Equation: Let's denote the unknown number as 'x'. According to the problem, sixty more than nine times the number (9x+60) is the same as two less than ten times the number (10x−2). We can set up the following equation to represent this relationship:9x+60=10x−2
Solve for x: Now, we need to solve for 'x'. Let's move all terms involving 'x' to one side and constant terms to the other side. We can subtract 9x from both sides to get:9x+60−9x=10x−2−9xThis simplifies to:60=x−2
Isolate x: Next, we add 2 to both sides to isolate 'x':60+2=x−2+2This gives us:62=x
Check Solution: We have found the value of x. To ensure there are no math errors, we can substitute x back into the original equation to check if both sides are equal:9x+60=10x−29(62)+60=10(62)−2558+60=620−2618=618Since both sides are equal, our solution is correct.
