Question

solve by substitution. 4x=6y+24. and 2x-3y=12

Answer 1

6y+24 = 4x
2x-3y=12
_______________

-4x+6y=-24
2x-3y=12

in second equation we localize x: 2x-3y=12 <==> x=(12+3y)/2
we substitute this wherever we have x in the first equation:
-4[(12+3y)/2]+6y=-24
just solve this to get y and replace wherever you have y in the equation where we localized x and you get y

Answer 2

how do you solve that though?
