Combine like terms. So, the total number of baseballs and tennis balls is

Explanation / Answer

STEP 1 :

For each box contain 12 base balls and the manager have total 14 base balls.

so the expression for base balls : 2 + (12)n    (for n = 1)

for tennis balls total 23 balls are there and each box contain 16 balls.

so the expression for tennis balls : 7 + (16)n (for n = 1)

STEP 2 :

combining two expressions

2 + (12)n + 7 + (16)n

2 + 7 + (12 + 16)n

9 + (28)n

so total number of base balls and tennis balls is 9 + (28)n

here n representing the number of boxes.

so for n=1 we will have 9 + (28)1 = 9 + 28 = 37

so total number of base balls and tennis balls is 14+23 = 37
