I'm going to rewrite this a little bit.

y=x+3

x=-2


You're given x so just plug that into the first equation. y=-2+3

y=1

4p + 3c and (c+2p)(2)
Tatiana [17]
\begin{gathered} 4p+3c=(c+2p)(2) \\ 4p+3c=2c+4p \\ 4p+3c-4p=2c+4p-4p \\ 3c\ne2c \\  \end{gathered}

since 3c is not equal to 2c, this means that the expressions are not equal

AC method, Factoring step by step I don't know how to do .
katrin2010 [14]

Answer:

(5a+4c)(2a-b)

Explanation:

Given the expression:

10a^2-5ab+8ac-4bc

First, group the expression into two:

=(10a^2-5ab)+(8ac-4bc)

• In the first group, 5a is a common factor.

,

• In the second group, 4c is a common factor.

Factor these out by dividing each term by the GCF of each group.

\begin{gathered} =5a(\frac{10a^2}{5a}-\frac{5ab}{5a})+4c(\frac{8ac}{4c}-\frac{4bc}{4c}) \\  \\ =5a(2a-b)+4c(2a-b) \end{gathered}

Since the terms inside the brackets are the same, combine:

=(5a+4c)(2a-b)

CHECK

To check if your result is correct in cases like these, expand as follows:

\begin{gathered} (5a+4c)(2a-b)=5a(2a-b)+4c(2a-b) \\ =10a^2-5ab+8ac-4bc \end{gathered}

Our result is the same as the original question, hence, the work is correct.
