1. The student changed -5x to -6x -1x. You can not simplify things like that, and it is not even equal to it’s original value.

2. The student correctly had x and -1 outside of the parenthesis, and should have stopped solving there. But those numbers totally vanished.

3·m - 2/3 - 2·m + 1/4 = 2/12

m - 2/3 + 1/4 = 2/12

m = 2/12 - 3/12 + 8/12

m = 7/12

Kenya plans to make a down payment plus monthly payments in order to buy a motorcycle. At one dealer she would pay $2,350 down a
vovangra [49]

Answer:

After 16 months, Kenya will have paid $5,550

Step-by-step explanation:

This is a guess and check type of a problem.  You guess a number of months, plug it into x, and see if both equations come out with the same answer.

 If you plug 16 into the first dealer's equation, you get y= 200(16) + 2350.  Solving this equation will mean y equals 5550.

If you plug 16 into the second dealer's equation, you get y= 175(16) + 2750.

Solving this equation will mean y also equals 5550.
