Question

(11) 2x + 5y - 1, 2x + 3y - 3​

Answer 1

Answer:

2x+5y-1+2x+3y-3

4x+8y-4

Answer 2

$2x + 5y - 1 = 0\: \: \: \: \: \: eq(i) \\ 2x + 3y - 3 = 0 \: \: \: \: \: \: eq(ii)$

from eq (i) we get

$=⟩x = \frac{1 - 5y}{2} \: \: \: \: \: \: \: \: ..eq(iii)$

Putting this value in eq (ii)

$=⟩2( \frac{ 1 - 5y}{2} ) + 3y = 3$

$=⟩1 - 5y + 3y = 3$

$=⟩ - 2y = 2$

$=⟩y = - 1$

Putting this value in eq ( iii )

$=⟩x = \frac{ 1 - 5( - 1)}{2}$

$=⟩x = \frac{1 + 5}{2}$

$=⟩x = \frac{6}{2}$

$=⟩x = 3$

Therefore , the value of x is 3 and the value of y is -1
