Question

Salve Elimination Methed
7y+10x=8

2Y-5x = 18
​

Answer 1

Answer:

2y-5x=18

multiply 2 to this eqn.then its becomes

4y-10x=36

7y+10x=8 now add these two eqn.

4y+7y-10x+10x=36+8

11y= 44

y=5

then apply this value in any eqn.

7y+10x=8

x=8-7y/10

x=8-35/10

x=-27/10

i hope u got that

mark this as brainliest ans if u got that

Answer 2

$\huge\boxed{\fcolorbox{red}{green}{answer}}$

$7y + 10x = 8......(1)$

$2y - 5x = 18.......(2)$

By using Elimination method

multiply 2 by equation...(2)

we get,

$=> 4y - 10x = 36$

Now equating the coefficient;

7y+10x=8

4y-10x=36

11y =44

=》 11y=44

=》 y=4

$put \: the \: value \: of \: y \: in \: equation \: (1)$

$= 7y + 10x = 8$

$= 7(4) + 10x = 8$

$= 28 + 10x = 8$

$= 10x = 8 - 28$

$= 10x = - 20$

$= x = - 2$

$the \: value \: of \: x = - 2 \: and \: \\ value \: of \: y = 4$
