Solve for x and y of the following eq. 4x+6/y=15 6x-8/y=14​

Answer»

ANSWER

x=2.65 and y=4.24

EXPLANATION

WE CAN SOLVE THIS WITH 2 WAYS

  • SUBSTITUTION
  • ELIMINATION

\large\mathcal\pink{SUBSTITUTION}

⟼4x+6/y=15

⟼4x=15y/6

⟼x=5y/8

Put the VALUE of x in 2nd equation

⟹6x-8/y=14

⟹30y/8-8/y=14

⟹15y/4-8/y=14

⟹(15y²-32)/4y=14

⟹15y²-32=56y

⟹15y²-56y-32=0

⟹y=4.24

put the value of y

⟼x=5y/8

⟼x=2.65
