Question

please explain how you get your answer
3x+4y=7
x=3-2y

Answer 1

Where did you get the -14y from?

Answer 2

Oh i see

Answer 3

3x+4y=7
x=3-2y

4y = 7 - 3x (*)
2y = 3 - x (**)

(*) - 3 time (**)

4y - 3(2y) = 7 - 3(3) - 3x - 3(-x)
4y - 6y = -2
-2y = -2
y = -2/-2
= 1

3x = 7 - 4y
= 7 - 4(1)
= 3

x = 1


Ans x = 1, y = 1
