Question

Place x = 3 in equation (I).
5 x ☐ + 3y = 9
Solution is (x, y) = ( ☐ , ☐)

Answer 1

Solution:-

given by :- 5 x ☐ + 3y = 9.........(1)

●when , x = 3
$then \\ ( x + 6)(x - y) = 9 \\ {x}^{2} - 6y + 6x - 6y = 9 \\ {x}^{2} + 6x - 12y = 9 \\ put \: x = 3 \\ 9 + 18 - 12y = 9 \\ - 12y = 9 - 27 \\ - 12y = - 18 \\ y = \frac{3}{2}$
put y's valeu in equation (1)
●5 x ☐ + 3y = 9..........(1)
●5×□ + 3×3/2 =9
●5×□ = 9 - 9/2
●5×□ = 9/2
● □ = 9/10

verification:-

●5×9/10+ 3×3/2 =9
● 9/2 + 9/2 =9
●9 = 9


[( x ,y ) = (9/10 , 3/2) ]ans
