Question

x + y = -1
4x+3y=10
find the value
of x, y.​
anyone plsss answer

Answer 1

Answer:

x=13

y= -14

Step-by-step explanation:

x+y= -1 ----------- eq1

4x+3y= 10--------- eq2

-3(x+y= -1). (Multiplying eq1 by -3)

-3x -3y= +3-----------eq3

Adding eq2 and eq3.

(4x+3y) +(-3x - 3y)=10+3

4x+3y-3x-3y=13

x=13

Since x+y = -1

or 13+y= -1

Therefore y= -14

Answer 2

Answer:

given,

x+y=-1.. .. (I)

4x+3y=10......(ii)

x=-1-y

putting the value of x=-1-y in equation second

4(-1-y) +3y=10

-4-4y+3y=10

-y=14

y= -14

so,

x=-1-(-14)

x=-1+14

x=13
