The sign rules for multiplying and dividing integers are the same.

There are three scenarios:

If you are multiplying/dividing two positive integers, your answer will be positive.

If you are multiplying/dividing two negative integers, your answer will be positive.

If you are multiplying/dividing one positive integers with one negative integer, your answer will be negative.

Mx=3c-4y

x=(3c-4y)/M

to solve for s you first have to isolate the term with the s in it. in order to get 9s isolated, I need to get rid of, or move, the 5g. to do this I add 5g to both sides.

9s=-4u+5g

I've isolated the term with the s in it, now I have to solve for s by dividing by its coefficient, 9.

s=(-4/9)u+(5/9)g 

the equation you would use is:

2+1.50x=8

this shows that $2 is a fixed amount (aka a constant) and the variable,x, represents time in hours being multiplied by $1.50 to determine how much to charge in the end.

Now, solve for x.

first subtract two from both sides and you have 1.50x=6

divide both sides by 1.50 and you get x=4

Remembering that $2 covered your first half hour, you can park for 4.5 hours for $8.
