I REALLY NEED HELP PLEASE

Nezavi [6.7K]

Answer:

Step-by-step explanation:

given

$\frac{s + ( - 7)}{ - 1}$

we first need to simplify the expression before we find it's value when s=-3

positive times negative=negative

so the equation becomes

$\frac{s - 7}{ - 1}$

substituting s=-3 into the equation.

$\frac{ - 3 - 7}{ - 1}$

$\frac{ - 10}{ - 1}$

=the negatives cancel out leaving

$= 10$

Solving systems equations by elimination

pishuonlain [190]

I won't answer them all for you (don't want to cheat - need to learn something).
But for the first one given:

<span>-2x-9y=-25
-4x-9y=-23

you set up either x or y (which ever one you want to eliminate) so that one of them cancels.
So this one is easy - you just have to multiply an entire row by negative (doesn't matter which one) - so that the y's will be + and -

Since they're both 9 and they're subracting NOW - you can eliminate the y value. Now add/subtract the x's. So it'd be -2 or 2 depending on how you eliminated y. Then add the number outside of the = sign. Now just solve for x. After that plug in whatever you got for x into both of the rows. Then find the y value.

Hopefully this wasn't confusing -- reply if it is and I will try to simplify. I can give you contact if you need help with the rest

Good luck!</span>
