Answer and Step-by-step explanation:

We are given: 18x - 2(3x + 1) = 5x - 16

First, lets distribute the -2 to the 3x and 1.

18x - 6x - 2 = 5x - 16

Now, we combine like terms.

12x - 2 = 5x - 16

Next, we add 2 to each side.

12x = 5x -14

Now, we subtract 5x from both sides.

7x = -14

Finally, we divide by 7 on both sides.

x = -2

  Statements:                             Reasons:

  18x - 2(3x + 1) = 5x - 16            Given

  18x - 6x - 2 = 5x - 16                Distributive Property of Equality

  12x - 2 = 5x - 16                       Combine like terms

  12x = 5x -14                              Addition Property of Equality

  7x = -14                                     Subtraction Property of Equality

  x = -2                                        Division Property of Equality

n200080 [17]

Answer: By the 8th week.

Step-by-step explanation:

Let the time that matteo and luca have the same amount of money be represented by x.

The information given in the question can be formed into an equation as:

400 - 10x = 200 + 15x

Collect like terms

400 - 200 = 15x + 10x

200 = 25x

x = 200/25

x = 8

Matteo and Luca will have the same amount of money by the 8th week.
