Answer:

24 weeks of lessons

Step-by-step explanation:

use y = mx + b

y = total pieces Colin can sing = 50

m = pieces learned each week of lessons = 2

x = number of weeks = ?

b = pieces colin knew before lessons = 2

50 = 2x + 2              (subtract 2 from both sides)

48 = 2x                     (divide both sides by 2)

x = 24 weeks
