Answer:
Explanation:
Represent this with two linear equations:
x+4 = y
x * y = 221
substitute for y:
y= 221/x
Plug this back into first equation:
221/x = x +4
x^2 + 4x = 221
x^2 + 4x -221 = 0
Solve this with a quadratic:
x = -17, x = 13
take the values of 17 and 13, which satisfy the given conditions
