Question from May, a parent: The difference between two numbers is 7. When the two numbers are multiplied the answer is 60. How do I work out the two numbers,I tried solving for one unknown and substitution and can not do it. Pleas show me how to do this. |
Hi May,
If the smaller of the two numbers is $x$ then the larger must be $x + 7.$ The product of $x$ and $x + 7$ is 60. Solve for $x.$
