Answer:

[tex]\displaystyle [\frac{9}{11}, 1\frac{111}{143}][/tex]

Step-by-step explanation:

{10x - 26y = −38

{6x + 13y = 28

½[10x - 26y = −38]

{5x - 13y = −19 >> New Equation

{6x + 13y = 28

___________

[tex]\displaystyle \frac{11x}{11} = \frac{9}{11}[/tex]

[tex]\displaystyle x = \frac{9}{11}[/tex][Plug this back into both equations above to get the y-coordinate of 1 111⁄143]; [tex]\displaystyle 1\frac{111}{143} = y[/tex]

I am joyous to assist you anytime.
