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♣
⟼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 |
