When using the elimination method to solve a system of equations, what is your goal?
To make one of the variable cancel out. (Same number, opposite sign!)

When solving equations, how do you move things away from the variable you are solving for? [how do you move things to the other side of an equation?]
Use the opposite operation. addition to cancel subtraction, division to undo multiplication. SADMEP

Jasmine is making a display board for the school
talent show. The display board is a 10 ft by 9 ft
rectangle. If ribbon costs $2 per foot, how much will
it cost to add a ribbon border around the entire
display board?

If you were to use substitution to solve the following system of equations, which variable in which equation would be the best one to solve for?
2x+y=5
-3x-6y=-18
the "y" in the first one. Because it has no coefficient.
300
What would be the best first step in solving this equation for "y"?
-2(3y+1)=10
distribute the -2. Because you can no start solving (moving things to the other side) until "y" is accessible.

Solve and graph the following inequality:
2x+9>25
x>7
[I can't make a graph on here, but it starts at 7, has an open dot (or parenthesis) and goes right]

If you were using elimination to solve this system of equations, what constant (an on which equation) would be the best one to multiply by?
3x-2y=7
-4x+6y=12
Multiply the top equation by 3 so the y's would cancel out.

Solve for "q"
-4(3q-2)+1=-3(-2q+4)
q= 7/6
[FRACTIONS ARE GOOD!]
So are negative numbers, don't be judgmental.

Simplify:
[(9x^2+3x^2)/x^2+6]/3+3
"9x^2" means the x is squared.
