Since you want both sides to equal each other, you can set up the following equation:
chess club members = computer club members
500 - 30x = 150 + 20x
x represents the amount of years that have passed. The coefficients for x represent the loss or gain of members per year.
Add 30x to both sides.
500 = 150 + 50x
Subtract 150 from both sides.
350 = 50x
Divide both sides by 50 to solve for x.
x = 7
It will take 7 years for both clubs to have the same amount of members.

Answer:
5
Step-by-step explanation:
Evaluate (h + k)(x) then substitute x = 2 into the result
(h + k)(x) = h(x) + k(x)
h(x) + k(x) = x² + 1 + x - 2 = x² + x - 1, thus
(h + k)(2) = 2² + 2 - 1 = 4 + 2 - 1 = 5
