Question

solve the pair of linear equation 2 X + 3 Y is equal to minus 4 and x minus 5 Y is equal to 11​

Answer 1

Answer:

$x=1 \\y=-2$

Step-by-step explanation:

$2x+3y=-4$     -(1)

$x-5y=11$    -(2)

Multiply equation (2) by 2.

$2x+3y=-4\\2(x-5y=11)$

Hence, subtracting cancels out 2x

$2x+3y=-4\\2x-10y=22$

With the change of signs,

$3y+10y=-4-22$

$13y=-26$

And, $y=-2$

Substitute the value of y in eqn (2)

$x-(5*-2)=11$

$x+10=11\\x=1$

Hence, $x=1 \\y=-2$

Hope it helps.

Answer 2

Answer:

HEY MATE YOUR ANSWER IS THIS

Step-by-step explanation:

2x+3y= -4 --------(1)

x-5y=11 -----------(2)

Multiply eqn (1) with 5 & eqn (2) with 3,

10x+15y= -20

3x-15y=33

13x =13

x=1

Putting the value of x in eqn 1,we get

2(1)+3y= -4

2+3y= -4

3y= -4-2

3y= -6

y = -6

3

y= -2

The value of (x,y) is (1, -2)

PLEASE I DID MUCH OF HARDWORK TO SOLVE THIS PLEASE GIVE ME SOME RATING.

THANK YOU.
