Question

The solution of the equation 2x+y=7 and 4x-3y+1=0​

Answer 1

Answer:

$2x + y - 7 = 0$

$4x - 3y + 1 = 0$

$by \: eliminating......$

$2x + y - 7 = 0( \times by \: 2)$

$4x + 2y - 14 = \: 0 \: (i)$

$4x - 3y + 1 = 0(ii)$

$by \: solving \: (i) \: and \: (ii)$

$y = 3 \: and \: x = 2$

Answer 2

Answer:

By elimination method

2x+y=7 -----1

4x-3y=-1 -----2

1×3. 6x+3y=21 ------3

3+2. 4x-3y=-1 --------2

10x=20

x=20/10

x=2

put value of x in equation 1

2×2+y=7

4+y=7

y=7-4

y=3

therefore x=2 and y=3
