Question

substitution
-x/6+y/2=1/2
x/3-y/6=-3/4

Answer 1

help @waterineyes

Answer 2

my y=-2x-9/2

Answer 3

Multiply first by 2 and second by 12 and show me what you get..

Answer 4

ok thanks

Answer 5

i.) -1/3X+Y=1
II.) 2X-2Y=-9

Answer 6

Sorry..

Answer 7

SORRY FOR?

Answer 8

multiply first with 6 and second with 12

Finally you will get:

-x + 3y = 3
4x - 2y = -9


Can you solve it now??

Answer 9

thanks I will try

Answer 10

x=3y-3

Answer 11

If you now multiply 4 with first equation then by adding x will get cancel and you can easily find y..

Try on your own and let me know the values of x and y you calculated..

I am waiting..

Answer 12

Yes: x = 3y - 3

Put it in second equation..

Answer 13

Multiply first by 2 and second by 12 and show me what you get..

Answer 14

then I will substitute it right?

Answer 15

Yes this method is called \(\color{green}{SUBSTITUTION}\)..

Answer 16

4x - 2y = -9 = 4(3y-3)-2y=-9
12y-2y=-9
10y=-9
y=-9/10?

Answer 17

No check it once more..

Answer 18

Where did -12 gone??

Answer 19

12y-12-2y=-9

Answer 20

Yes go ahead.

Answer 21

12y-2y=-9+12

Answer 22

Yes have faith just do the steps..

Answer 23

10y=3
y=3/10?

Answer 24

Yes now find x:

x = 3y - 3

Answer 25

x=3(3/10)-3
x=9/10-3
x=-21/10

Answer 26

Yes, you have done it very correctly..

A medal for you from my side..
