Question

Is the pair of numbers x=1 5/7 and y=4 2/7 the solution to the equation x+y=6? Find two more solutions to the equation.

Answer 1

Yes 1 5/7 and 4 2/7 is a solution. Adding those two numbers equals 6 because 5/7 + 2/7 = 1, then you have 4 + 1 +1 = 6

Two other solutions to x + y = 6 are any combinations of numbers when added together equal 6.

x = 5, y = 1

and

x = 2, y = 4
