Question

someone please tell me solution for 2y-6=5x and y-x=9 by eliminating the equation​

Answer 1

Answer:

try it yourself

don't depend on other

Answer 2

Answer:

2y - 6 =5x

-5x + 2y = 6 -------> eqn 1

y - x = 9

-x + y =9 ------> eqn 2

eqn 2 * 5

-5x + 5y = 45 -----> eqn 3

eqn 1 - eqn 3

  -5x + 2y = 6

- (-5x + 5y = 45)

        - 3y   = - 39

            y = -39/-3

           y  = 13

-x + y = 9

- x + 13= 9

-x  = 9 - 13

-x    = - 4

x  = 4
