Answer:

223/29

Step-by-step explanation:

5x+3y=10 . multiply by 4

3x-4y=61 . multiply by 3

20x+12y=40

+ 9x-12y=183

_____________

29x-0y = 223 . divide both sides by 29

x = 223/29

X~4y=11 , 5x~7y=~10 system of equation using elimination to solve

tino4ka555 [31]

1x + 4y = 11 ⇒ 5x + 20y = 55
5x - 7y = -10 ⇒ 5x - 7y = -10
 27y = 65
 27 27
 y = 2¹¹/₂₇
 x + 4(2¹¹/₂₇) = 11
 x + 8²²/₂₇ = 11
 - 8²²/₂₇ - 8²²/₂₇
 x = 2⁵/₂₇
 (x, y) = (2⁵/₂₇, 2¹¹/₂₇)
