Step-by-step explanation:

system of equations:

a+b=4

a^3+b^3=28

a=4-b

plug in for a in other equation and solve

(4-b)^3+b^3=28

64-48b+12b^2-b^3+b^3=28

64-48b+12b^2=28

0=36-48b+12b^2

0=3-4b+b^2

0=(b-3)(b-1)

b = 3

b=1

plug into other equation to get a

a=4-b=4-3=1

a=4-b=4-1=3

multiply together

1*3=3
