Answer:

Step-by-step explanation:

First you need to find x.

It is shown that DE=EF, so we can use this.

5x-3=3x+7

5x=3x+10

2x=10

x=5

Then, you plug in the value of the variable and solve.

6(5)-3

30-3

Is (10,-10) a common solution for x-5>3 and -y>7?

fenix001 [56]

$\bf (\stackrel{x}{10}~~,~~\stackrel{y}{-10})
\\\\\\
\begin{cases}
x-5\ \textgreater \ 3\\
-y\ \textgreater \ 7
\end{cases}$

is it? let's check.

x-5>3 x = 10

(10) - 5 > 3

5 > 3 <----- hmmm is that really true? 5 is indeed greater than 3.

let's check the other condition, "y" being -10.

-y > 7 y = -10

-(-10) > 7

+10 > 7 <---- is 10 greater than 7 really? well, yes it is.

since the coordinates of 10, -10, provide a "true" value for each inequality, then 10,-10 is a solution.
