The sum of two numbers is 52 and the difference is 16. What are the numbers?
You have to set this up in 2 different equations, using 2 different unknowns. The 2 numbers can be x and y. What does "sum" mean?
Using "x" and "y," and the sum value 52, write an equation for "the sum of two numbers."
"The sum of two numbers is 52," x + y = 52 y = (52-x)
good!
so i just have to add something to 16 to get the sum which is 52?
Not quite. You are to come up with 2 separate equations, and then to solve these equations simultaneously to obtain values for the variables x and y. x+y-52 Write an equation for "the difference between the two numbers is 16."
sum: addition x+y=52 difference: subtraction: write the equation here. Solve this system of linear equations, preferably by addition / subtraction.
