Question

solve by substitution
-6x=-9-y
2y-12x=18

Answer 1

if you were to solve for "y"
-6x=-9-y

what would that look like?

Answer 2

can you explain the steps

Answer 3

-6x=-9-y
# add +y to each side
-6x + y = -9-y+y => -6x+y = -9
# add 6x to each side
-6x+y+6x = -9+6x => ?

Answer 4

(2,3)

Answer 5

?

Answer 6

well, is not that, what would the equation give you at
# add 6x to each side
-6x+y+6x = -9+6x => ????

Answer 7

(3,9) ?

Answer 8

you'd firstly need to solve for "y"
-6x+y+6x = -9+6x

Answer 9

so, cancelling like terms there would give you, a "y" you can use

Answer 10

no solution? thats my last option

Answer 11

or your can solve for "y" on that one above
