6=2(y+2) y=?

please help​

Explanation:

There are two ways to solve this

The first method will have us distribute the 2 through to each term, then we solve for y

6 = 2(y+2)

6 = 2y+4 distribute

2y+4 = 6

2y = 6-4 subtract 4 from both sides

2y = 2

y = 2/2 divide both sides by 2

y = 1 is the answer

Or we can solve through this set of steps

6 = 2(y+2)

6/2 = y+2 divide both sides by 2

3 = y+2

y+2 = 3

y = 3-2 subtract 2 from both sides

y = 1

Either way, we get the same answer.

To check the answer, replace every copy of y with 1

Simplifying should lead to 6 on the right side

6 = 2(y+2)

6 = 2(1+2)

6 = 2(3)

6 = 6

Since we get the same thing on both sides, this means the last equation is true. This in turn means the first equation is true when y = 1. Therefore, the solution has been confirmed.

Step-by-step explanation:

Focus of a Parabola. A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix. The focus lies on the axis of symmetry of the parabola.
