Matthew is organizing textbooks on his bookshelf. He has a Spanish textbook, a biology textbook, and a history textbook. How many different ways can he line the textbooks up on his bookshelf?

I think he can line them up a total of 6 times?

6

Step-by-step explanation:

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

5x+10 is the correct one

hope this
