For the following system, use the second equation to make a substitution for y in the first equation. 3x + y = 1 y + 4 = 5x What

Debora [2.8K]

Answer:

The answer is A.

Step-by-step explanation:

So we have the two equations:

$3x+y=1\\y+4=5x$

To make a substitution of the second equation into the first equation, we need to isolate the y variable in the second equation. Thus:

$y+4=5x\\y=5x-4$

Now, we can substitute this into the first equation. Therefore:

$3x+y=1\\3x+(5x-4)=1\\3x+5x-4=1$

Answer:

the answer is $\sqrt{5\\}$ , and - $\sqrt{5\\}$ which is C.

Step-by-step explanation:

well I got that answer by doing this

we have $x^{2}$ = 5

For $x^{2}$ = f (a) the solutions are x = $\sqrt{f(a)\\}$ , - $\sqrt{f(a)\\}$

so in this case the solutions are $\sqrt{5\\}$ , and - $\sqrt{5\\}$
