Question

The co-ordinates of the points where the lines 3x - y = 5, 6x - y = 10 meet
they axis
(A) (0-5), (0.-10)
(B) (-5, 0.1-10,0)
(C) -5,0), (0, -10)
(D) (0,5), (0, 10)
​

Answer 1

Answer:

option a is correct answer

Answer 2

$Given \: system \:of \: equations : \\i ) 3x - y = 5 \\\implies y = 3x - 5 \: ---(1)$

$ii) 6x - y = 10 \\\implies y = 6x - 10 \: ---(2)$

/* From equations (1) and (2), we get */

$(2) = (1)$

$\implies 6x - 10 = 3x - 5$

$\implies 6x - 3x = - 5 + 10$

$\implies 3x = 5$

$\implies x = \frac{5 }{3}$

$Put\: x = \frac{5 }{3} \:in \: equation \:(1), \:we \\get$

$y = 3 \times \frac{5 }{3} - 5$

$\implies y = 5 - 5$

$\implies y = 0$

Therefore.,

$\red{ Intersecting \:point\: of \: above}\\\red{ \:equations } \\\green{ = ( \frac{5}{3} , 0 ) }$

$Given \:options \:are \: wrong$
