Answer:

1) x=3, y=-3

Step-by-step explanation:

10x + 7y = 9 —— (1)

-4x -7y = 9 —— (2)

(1) + (2)

6x = 18

x = 18/6

x = 3

put x=3 in (1)

10(3) + 7y = 9

30 + 7y = 9

7y = 9 - 30

7y = -21

y = -21/7

y = -3

Answer:

The question is not correct. you have two linear functions. do you want to know their intersection point?

Step-by-step explanation:

[tex]f(x)=2x-6\\[/tex]

[tex]2x-6=0[/tex]

[tex]2x=6[/tex]

[tex]\frac{2x}{2} =\frac{6}{2\\}[/tex]
