Answer:

x=2, y=8 or (2, 8)

Step-by-step explanation:

y=3x+2

y=7x-6

substitute y=7x-6 into y=3x+2

7x-6=3x+2

4x=8

x=2

then plug 2 into either one

y=7(2)-6

y=8

Check answers

8=3(2) + 2 | correct

8 =7(2)-6 | correct

The sum of 3 consecutive integers is 78. What is the integer closest to zero?

vova2212 [387]

Answer:

25

Step-by-step explanation:

Let n be the first integer.

Then the second integer will be (n + 1).

And the third will be (n + 2).

The sum is 78. Therefore:

$n+(n+1)+(n+2)+78$

Solve for n. Combine like terms:

$3n+3=78$

So:

$3n=75$

Therefore:

$n=25$

Therefore, the first integer is 25.

So our sequene is 25, 26, and 27.

The integer closest to zero will thus be 25.
