Question

The sum of two numbers is 22. Two less than three times the smaller number is equal to the larger number x. Find the larger number.

Answer 1

y=6, x=16

you create a system with the two variables and manipulate an equation so that you can substitute in the other to make it a single-variable equation. you then solve for that variable by isolating it and you can solve for the second variable afterwards. hope this helps!
