q + p
2q ÷ q = 2
Call the numbers p and q. From the problem statement, p - q = 16 and p + q = 58. From the first of these, p = q + 16. Substitute this in the second to result in q + 16 + q = 58, or 2q = 58 - 16, or q = 21, and p = 37. Alternatively 58 - 16 = 42. 42/2 = 21 and 21 + 16 = 37. Same result, different method.

By factoring. q2 + 16q = 0 q (q + 16) = 0 Now, either q = 0, or q + 16 = 0. Solve those two equations to get the solution.
16/q
if q+9=16 q=16-9 q= 7
q + p
xq/f q divided by f is the fraction q/f
2q ÷ q = 2
p divided by q.
q = 78
Call the numbers p and q. From the problem statement, p - q = 16 and p + q = 58. From the first of these, p = q + 16. Substitute this in the second to result in q + 16 + q = 58, or 2q = 58 - 16, or q = 21, and p = 37. Alternatively 58 - 16 = 42. 42/2 = 21 and 21 + 16 = 37. Same result, different method.
