Answer: multiply x by 2 in the first equation and subtract the second equation

Step-by-step explanation:

To solve a system of linear equations by elimination method , our first step is to make its (either x or y) coefficient same.

For that we multiply a number to both sides of the equation not to only one term.

So by checking all the given options it is pretty clear that the last option is not applicable for elimination method because in this 2 is multiplied to only one term, which proceeds to loose the balance of the equation.

Thus , an INCORRECT step that will NOT produce a system with the same solution is "multiply x by 2 in the first equation and subtract the second equation ".

Answer:

Cr = 10

Step-by-step explanation:

To calculate combinations we use the nCr formula: nCr = n! / r! * (n - r)!, where n = number of items, and r = number of items being chosen at a time.

$C(n,r)=[?]$
