Question

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

Answer 1

✠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
