Set up a system of equations:
2x+3y=6
x-3y=9
You can solve this with elimination by adding the two equations together:
3x+0y = 15
3x=15
x=5
Then, plug this value back into either of the original equations to find the y value:
5-3y=9
-3y=4
y= -4/3
The point of intersection is (5,-4/3)

Let's solve this inequality!

What can we do to solve this inequality? Well, first of all, we can add -7 and 35:

Now, move 20 to the right, using the opposite operation:

Subtract:

Divide both sides by -1 to isolate x:
(Answer)
_____________
<em>Additional comment</em>
When we divide both sides of an inequality by a negative number, we flip the inequality sign.

Answer:
d=-8
Step-by-step explanation:
-8 × -4=+32 ....always remember a positive number and negative number equals a negative number and negative number times a negative number is a positive number
Answer:

Step-by-step explanation:
The given equation is 
We want to rearrange this equation so that, n becomes the independent variable.
This means we must solve form, m which becomes the dependent variable.
We expand the parenthesis to get:

We now subtract 1 from both sides to obtain:

We simplify to obtain:

This can be rewritten as
