Answer:

Step-by-step explanation:

-x + 3y =9

substitute y with 2/3x as mentioned in the question

so,

-x+3 (2/3x) = 9

cancelling 3 we get..

-x+2x=9

x=9

hope it helps

thanks

Answer:

y = 6

Step-by-step explanation:

- x + 3y = 9 ( add x to both sides )

3y = 9 + x → (1)

y = [tex]\frac{2}{3}[/tex] x ( multiply both sides by 3 to clear the fraction )

3y = 2x → (2)

substitute 3y = 2x into (1)

2x = 9 + x ( subtract x from both sides )

x = 9

substitute x = 9 into (1)

3y = 9 + 9 = 18 ( divide both sides by 3 )

y = 6
