Question

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

Answer 1

I'll do the left side.

1:

`-6=(n)/(3) -8 \\2 = (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 = (n)/(4) - 3 \\-4 = (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

`(-6)/(5) = y`

`-6 + (x)/(2) = -3\\ (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!!!
