Answer 1

Full Question Please

Answer 2

hint: how can you get the coefficients of y to be equal?

Answer 3

What is the point of multiply by 6? I don't see any question saying multiply

Answer 4

nvm i see

Answer 5

1

Answer 6

hint: multiply the first equation by 2 and let me know what you get

Answer 7

6x-2y=0

Answer 8

awesome, so you would write the new system of equations, replacing equation 1 by this new equation

Answer 9

new system:

6x - 2y = 0
5x + 2y = 22

Answer 10

and that's it for part I

Answer 11

okay now for part II

Answer 12

for part II add the two equations together and you will be able to eliminate y.

Answer 13

11x=22

Answer 14

good that's it for p II

Answer 15

for part III just solve for x

Answer 16

x=2

Answer 17

awesome that's it for III
for IV just substitute x = 2 into one of the original equations and solve for y

Answer 18

3x - y = 0

let x = 2 and solve for y.

Answer 19

y=6

Answer 20

oh I used the second equation to solve for y :S

Answer 21

good so your solution is (2,6)

Answer 22

it doesn't matter you can use either equation
