8(3)-3y=12 What is y in this equation

iVinArrow [24]

8(3) - 3y = 12

First, multiply 8 × 3 to get 24.
$24 - 3y = 12$
Second, subtract '24' from both sides.
$-3y = 12 - 24$
Third, subtract '12 - 24' to get '-12'.
$-3y = -12$
Fourth, divide both sides by '-3'.
$y = \frac{-12}{-3}$
Fifth, change the whole fraction to a negative.
$y = \frac{12}{3}$
Sixth, 12 ÷ 3 = 4. Simplify your fraction to 4.
$y = 4$

Answer: y = 4

Leya [2.2K]

Given :

The Dobson exit is halfway between the Mt. Airy exit and the Elkin exit. If the Elkin exit is located at (-5,-2) and the Dobson exit is located at (-1,4).

To Find :

How far is it from the Elkin exit to the Mt. Airy exit.

Solution :

E(-5,-2) , D(-1 ,4 ) .

It is also given that Dobson exit is halfway between the Mt. Airy exit and the Elkin exit.

Let , location of Elkin exit is A(h,k) .

So , point D in terms of A and E is given by :

$(\dfrac{h-5}{2},\dfrac{k-2}{2})$ .
