Question

solve x and y by substution method
2x+5y=8/3
3x-2y=5/6​

Answer 1

Answer:

$2x + 5y = \frac{8}{3} \\ 6x + 15y = 8 \: \: \: \: \: \: \: \: ...(1) \\ 3x - 2y = \frac{5}{6} \: \: \: \: \: \: \: \\ 18x - 12y = 5 \: \: \: \: \: \: \: \: ...(2) \\ multipying \: equation \: (1) \: by \: 3 \\ we \: get \\ 18x + 45y = 24 \: \: \: \: \: \: \: \: ...(3) \\ equation(3) - equation(2) \\ we \: get \\ 52y = 19 \\ y = \frac{19}{52 } \\ substituting \: the \: value \: o f\: y \: in \: eq \: (1) \\ we \: get \\ x = \frac{131}{312}$

this is your answer hope it helps to you☺️
