Solve for x. In the equation 9x +1/3= x-13

Step-by-step explanation:

9x+=x-13

9x*3+1/3=x-13

27x-1/3=x-13

27x-1=3(x-13)

27x-1=3x-39

27x-3x=-39+1

24x=-38

x=-38/24

x=-19/12

x = -

Step-by-step explanation:

Given

9x + = x - 13 ( multiply through by 3 to clear the fraction )

27x + 1 = 3x - 39 ( subtract 3x from both sides )

24x + 1 = - 39 ( subtract 1 from both sides )

24x = - 40 ( divide both sides by 24 )

x = = -

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
