Question

Im kind of confused What am i supposed to do?

Answer 1

Club A:   25+30x   where x is the number of lesson

Club B   55 + 20x where x is the number of lesson

when is the cost equal

25+ 30x = 55 + 20x

subtract 20 x from each side

25+ 30x -20x = 55 - 20x

25+ 10x = 55

subtract 25 from each side

25-25+ 10x = 55 - 25

10 x = 30

divide by 10

10x/10 = 30/10

x = 3

After 3 lessons the cost is equal
