let "one number" = x, and "another" = y
x = 4y + 4
(x + y) - 4 = 28
Plug in 4y + 4 for x
4y + 4 + y - 4 = 28
Simplify. Combine like terms
5y = 28
Isolate the y. Divide 5 from both sides
y = 28/5
y = 5.6
Plug in 28/5 for y.
x = 4y + 4
x = 4(28/5) + 4
Simplify
x = 22.4 + 4
x = 26.4
x = 26.4, y = 5.6
hope this helps
