A system of equations. x plus y equals 28. x equals 3 plus y. A system of equations. x y equals 28. x equals 3 y. A system of equations. x y equals 28. x equals 3 plus y. A system of equations. x plus y equals 28. x equals 3 y.

Answer 1

Answer:

x+y=28

x=3y

Step-by-step explanation:

This is because the sum of numbers x and y i.e. x+y make up 28

If x is three times y, then 3*y is represented as 3y hence x=3y
