Question

Solve the system by using elimination or elimination with multiplication.
3x - 2y = 9 and -3x + 2y = -9

Solve the system by using elimination or elimination with multiplication. One point for the steps and one point for the correct solution.
3x + 4y = -2 and 2x - 3y = 10

Answer 1

3x + 4y = -2
2x - 3y = 10


3x + 4y = -2
x=(-2-4y)/3

2x - 3y = 10
2(-2-4y)/3 - 3y = 10

( (-4-8y)/3-3y=10 ) * 3
-4-8y-9y=30
-4-17y=30
y=2

Answer 2

3x - 2y = 9 and -3x + 2y = -9

u won't able to find the value of x and y with using the same equation

Answer 3

you have infinite solutions to this equation ... all points lying on the line are solutions

Answer 4

for the first one? u sure its not no solution?
