Based on the given above, collection of books of Nathan and Jason can be translated into the following equations:
6J + 1/3N = 134
1/3 J + N = 31; J = Jasons and N=Nathan
Solving two equations with two unknowns simultaneously,
Jason = 21 books and Nathan = 24 books
To solve this you must isolate x. First add 1 to both sides
x² - 1 + 1 = 0 + 1
x² = 1
Now you must take the square root of both sides to cancel out the square from the x
√x² = √1
x = 1 and x = -1
When you take the square root of a number you must remember to take both the positive and negative of the number
Hope this helped!

Answer:
60
Step-by-step explanation:
Since the perimeters are equal then:
(3x + 3) * 4 = (x + 8) * 5
12x + 12 = 5x + 40
7x = 28
x =4
Perimeter of square = (3*4 + 3) * 4 =
(12 + 3) * 4 = 60
Perimeter of pentagon = (4 + 8) * 5 =
(12) * 5 = 60
The answer is 60
