Question 1
1.
For the system shown below,
5x + 3y = 5
5x - 2y = 7
Which variable can be eliminated (gives 0), IF POSSIBLE, and must you add or subtract to make it cancel?
can eliminate x's by adding
can eliminate y's by adding
can eliminate x's by subtracting
can eliminate y's by subtracting
NO variable can be eliminated YET
Question 2
2.

Which variable can be eliminated (gives 0), IF POSSIBLE, and must you add or subtract to make it cancel?
can eliminate x's by adding
can eliminate y's by adding
can eliminate x's by subtracting
can eliminate y's by subtracting

Question 3
3.
You can eliminate one variable and solve for the first answer in the system below right from the start.
What is the
FIRST ANSWER (ONLY!)
that you can get from the system?
Work it out in your notebook!!
4x + 3y = 24
4x + y = 16
x = 3
y = 4
x = 4
y = 2
Question 4
4.
THIS IS A CONTINUATION OF PROBLEM 3.
Use your
answer from Problem 3
and find the answer for the
OTHER
variable.
Type your answer in the space belolw. Ex. x = 9; OR y = -5, etc.
Work it out in your notebook!!
4x + 3y = 24
4x + y = 16

3x + 2y = 8
2x - 2y = 2
x = 2
y = 1
x = 6
y = 10
Question 6
