Answer:

All real numbers would be the solution

Step-by-step explanation:

2y - 4x =2 and y = 2x + 1

We solve but placing the value of y into the first equation:

2(2x + 1) - 4x = 2

Next we distribute the 2 through the parenthesis:

4x + 2 - 4x = 2

Now we gather like terms:

2 = 2 ( note the 4x and - 4x cancel out)

Since 2 =2 this tells us that all real numbers would work.

Factor out the following by taking out the GCF18cd^2+12c^2d+9cd

Arturiano [62]

The given polynomial is:

$18cd^2+12c^2d+9cd$

The first step to factor taking out the GCF is to write each term in prime factored form, so:

$\begin{gathered} 18cd^2=2\times3\times3\times c\times d\times d \\ 12c^2d=2\times2\times3\times c\times c\times d \\ 9cd=3\times3\times c\times d \end{gathered}$

The second step is to identify the factors common in all terms, they are: 3xcxd

Finally, factor out the GCF:

$3cd(6d+4c+3)$

The answer is above
