2n - 3 = 9

If you are solving for n:

Isolate it by doing the opposite of PEMDAS; Also, what you do to one side you do to the other (because of the equal sign)


2n - 3 = 9

2n - 3 (+3) = 9 (+3)

2n = 12

2n/2 = 12/2

n = 6

n = 6 is your answer

hope this helps

2n-3=9
------------
Add 3 to each side
2n−3+3=9+3
2n = 12
------------------
Divide each side by 2
2n ÷ 2 = 12 ÷ 2
n = 6

X - 2y = 3<br> 5x + 3y = 2<br> The lines whose equations are shown intersect at which point?
Lady_Fox [76]

The point of intersection of the two lines is at (1,-1)

<h3>System of equation</h3>

The given system of expression is shown below

x - 2y = 3

5x + 3y = 2

The solution to the system of equation is the point of intersection

From equation 1

x = 3 + 2y

Substitute into 2

5(3+2y) + 3y = 2

15 +10y + 3y = 2

13y = -13

y = -1

Substitute y = -1 into 3

x = 3 + 2y

x = 3+(-2)

x = 1

Hence the point of intersection of the two lines is at (1,-1)
