Question

Can someone please give me the awnsers !!!!!!

Answer 1

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 coefficient 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

Everything in math builds on this!!!
