Question

I need help plsssssssss

Answer 1

`- x = - 1 - 9y \\ ( - x)/( - 1) = ( - 1)/( - 1) - (9)/( - 1) \\ x = 1 + 9y...(3) \\ 3(1 + 9y) - 3y = 9 \\ 3 + 27y - 3y = 9 \\ 3 + 24y = 9 \\ 24y = 9 - 3 \\ 24y = 6 \\ (24y)/(24) = (6)/(24) \\ y = (1)/(4) \\ \\ \\ \\ x = 9( (1)/(4) ) + 1 \\ x = (9)/(4) + 1 \\ x = (13)/(4)`

Explanation:

ATTACHED IS THE SOLUTION!

Answer 2

x = 1

y = -2

Explanation:

x = 19 + 9y

3x- 3y = 9

________

3(19+9y)-3y=9

y=-2

x=19+9(-2)

x=1

(1,-2)
