It cost $60 to be a member of a music club a member of the club pays $20 per music lesson a non-member pays 35 per music wasn't how many music lessons must a member in non-member take so the cost of each has the same

Let x represent the number of music lessons taken. Then the cost for x music lessons for a member is 20x+150 and the cost for x music lessons for a non-member is 35x. The break-even point is when these two quantities are equal, so solve:

35x=20x+150
