Can someone help me figure this out. The difference of two numbers is 80. The second is 8 less than 5 times the first. What are the two numbers?
first write an equation 5x-8=y and then solve it
Tiff gave you part of the solution.
5x-8=y
However, there is the other equation.
x-y=80
Solve one equation for either unknown, then substitute that value for the unknown in the other equation. Once you find that first unknown, solve for the second. Check by substituting the values into both equations.
I hope this helps a little more. Thanks for asking.
