Answer:

x=−7/5and y=−6/5

Step-by-step explanation:

Step: Substitute−2x−4foryiny=3x+3:

y=3x+3

−2x−4=3x+3

−2x−4+−3x=3x+3+−3x(Add -3x to both sides)

−5x−4=3

−5x−4+4=3+4(Add 4 to both sides)

−5x=7

−5x

−5

=

7

−5

(Divide both sides by -5)

x=−7/5

Which student correctly used guess and check to determine the unknown number?
Alenkasestr [34]
<h2>Explanation:</h2><h2></h2>

Hello! Remember you need to write complete questions in order to get good and exact answers. Here we know nothing about the students so I can only help you providing the correct steps to find <em>the product of a number and eight is 104:</em>

<em />

Let that number be n, then the statement can be written in a mathematical language as follows:

n\times 8=104 \\ \\ \\ \text{Dividing both sides by 8:} \\ \\ \frac{n\times 8}{8}=\frac{104}{8} \\ \\ \boxed{n=13}

Finally, <em>the unknown number is 13</em>
