I'll do the left side.

1:

-6=\frac{n}{3}  -8 \\2 = \frac{n}{3} \\n = 6

Inverses are your friends, for example to get n - 3 = 0 where n is on one side, do the inverse of subtraction ( addition) so you get n - 3 + 3 = 3 \\\\n = 3

-7 = \frac{n}{4} - 3 \\-4 = \frac{n}{4}\\n = -16

-13 = 5y + 7 \\-6 = 5y \\

On "y" there is a <em>coefficient </em>of 5, aka 5*y,  the inverse of multiplication is division

\frac{-6}{5} = y

-6 + \frac{x}{2} = -3\\ \frac{x}{2} = 3 \\x = 6

You finish the rest, but you gotta remember this, isolate the variable (x, y, z, whatever) by doing inverses

inverses

addition - subtraction

multiplication - division

<em>Everything in math builds on this!!!</em>

is it possible to have three points that would not fit on the same plane 2 dimensional surface? Why or why not
Alisiya [41]
<span>No. Three points could be the three points of a triangle. Triangles are two dimensional surfaces. Therefore, any three points could exist on a two dimensional triangle.</span>

take a pair of two's and a pair of three's out of the radical sign:

5√72 = 5*2*3√2 = 30√2

this is the simplest radical form
