Before beginning voice lessons, Bryan already knew how to sing 146 pieces, and he expects to learn 2 new pieces during each week of lessons. How many weeks of lessons will Bryan need before he will be able to sing a total of 300 pieces? Write and Solve an equation to find the answer.

77 weeks

Step-by-step explanation:

Let the number of weeks be represented as x

The equation for the above question is given as:

146 + 2(x) = 300 pieces

146 + 2x = 300

2x = 300 - 146

2x = 154

x = 154/2

x = 77

Bryan would be needing 77 weeks of lessons
