Accepted Solution
In mathematical problems, when you're asked to find an unknown variable, it's common to use the symbol 'x' to represent this unknown value. So, in a problem such as "What number 'x', when divided by 9, equals 70?", we're tasked with determining the unknown 'x' value in the equation $\frac {x}{9} = 70$.
Once the problem is set up as an equation, the goal is to isolate 'x'. In this case, multiplying both sides of the equation by 9 gives us $x = 70*9$. Now we simplify that to get the final answer $x = 630$.
To confirm the validity of our solution, we substitute 'x' with 630 in the original equation: $\frac {630}{9} = 70$. As the equation holds true, our answer is proven correct.
