so that u get 6x there also

Answer 3

first add 6x to both sides of 1st equation

Answer 4

ok

Answer 5

-8-6x=-7y
3=-6x+18/4y

Answer 6

Answer 8

-8=6x-7y

Answer 9

ok what now?

Answer 10

-8=6x-7y
3=-6x+(9/2)y
now add these equations

Answer 11

-5=-5/2y

Answer 12

-7+9/2 = -14+9 /2 = -5/2
yes, its correct :)
so
-5 = -(5/2) y
y= ?

Answer 13

-(5/2)

Answer 14

y= -5 * (-2/5) = +2

Answer 15

why +2

Answer 16

\(\huge y=\frac{-2}{5}\times(-5)=-2\times(-1)=2\)

Answer 17

ok got it:)

Answer 18

now find x , put y=2

Answer 19

-8-6x=-14
3=-x+6/4y

Answer 20
