Let x be the number of rows. We solve the equation: x * ( 2 + 3 ) = 150. x * 5 = 150. x = 150 ÷ 5 . x = 30. a. There are 2 * 30 = 60 seats on the left side of the plane. b. There are 3 * 30 = 90 seats on the right side of the plane.

Every row is the same with 2 seats on the left and 3 seats on the right. That means that what is true of one row is true of all rows combined.
In one row there are 5 seat (2 + 3 = 5). There are 2 seats on the left, so the seat on the left are 2/5 of the seats. The 3 seats on the right are 3/5 of the seats.
