3x - 4y = -18

Question

Choose the equivalent system of linear equations that will produce the same solution as the one given below.

6x + 2y = -6
3x - 4y = -18

anonymous · Answer

12x + 4y = -12
15x = -30

 8x + 4y = -4
14x = -10

 6x - 8y = -36
-6y = -42

 6x - y = -15
3y = 9

solve these two equations for "x" and "y" and same with the below too... the similar values will show the equality... 

6x + 2y = -6 
3x - 4y = -18

anonymous · Answer

ok gimme a sec

anonymous · Answer

for the first i got y=-3 and x=0

paki · Answer

hmmm... now perform the same for the below equations too... the similar set values are the required similar equations....

anonymous · Answer

for the 2nd one i got y=4.5 and x=-6

paki · Answer

are these values rite... mean your calculation is rite at all...?

anonymous · Answer

i wasnt talking bout the first two ansers i did it for these two 6x + 2y = -6
3x - 4y = -18

anonymous · Answer

but idk
 if there rigth or not

paki · Answer

how you obtained (y=-3 and x=0)... can you show me your work here...

anonymous · Answer

$$6x+2y=-6~take~out~the~6x~then~solve~for~ 2y=-6$$ thats what i do to solve for the certain variables

paki · Answer

NO....you did it wrong...

anonymous · Answer

thats what my teacher said to do but it might just be for something else i dont remember thats why i need help

paki · Answer

look at this... we will solve this like.... http://openstudy.com/study#/updates/52a0df3ee4b01a67794f53f3
