If x=5 and y=-2 , then find the value of (i) `(8x-2y+5)/(2x+4ty+12) " "(ii) (5x-6y-7)/(3x+6y+12)` |
Answer» Correct Answer - (i) `(7)/(2)` (ii) 2 x=5, y=-2 (i) `(8x-2y+5)/(2x+4y-10)=(8xx5-2xx(-2)+5)/(2xx5+4(-2)-10)` `=(40+4+5)/(10-8+12)` `=(49)/(14)=(7)/(2)` `(ii) (5x-6y-7)/(3x+6y+12)=(5xx5-6(-2)-7)/(3xx5+6(-2)+12)` `=(25+12-7)/(15-12+12)` `=(30)/(15)=2` |
