Me write the equation for the problem below a chess club has 500 members but is losing 30 members each year. a computer club has 150 members and is gaining 20 members per year. wrote and solve an equation to find the number of years it will take for the two clubs to have the same number of members.

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.
