Can Someone Please Give Me The Awnsers class=

Sagot :

I'll do the left side.

1:

[tex]-6=\frac{n}{3} -8 \\2 = \frac{n}{3} \\n = 6[/tex]

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

[tex]-7 = \frac{n}{4} - 3 \\-4 = \frac{n}{4}\\n = -16[/tex]

[tex]-13 = 5y + 7 \\-6 = 5y \\[/tex]

On "y" there is a coefficient of 5, aka [tex]5*y[/tex],  the inverse of multiplication is division

[tex]\frac{-6}{5} = y[/tex]

[tex]-6 + \frac{x}{2} = -3\\ \frac{x}{2} = 3 \\x = 6[/tex]

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!!!
