Question

solve following system of linera equqtions 4X+ 2Y=8 3X-Y=-1​

Answer 1

Answer:

4x+2y=8 3x-y=-1

4x-3x=-y-2y=-1-8

x=3y=9

Answer 2

4x+2y=8------1

Step-by-step explanation:

Now we solve equation 1

4x=8-2y

X=8-2y/4------2

3x-y= -1--------3

now putting the value of x in equation 3 we get

3x-y= -1

3(8-2y/4)-y= -1

24-6y-4y= -4

-10y= -28

so y=14/5

now putting the value of y in equation 2 we get

X=8-2y/4

X=8-2(14/5)/4

X=3/5

Hence,the value of x=3/5 and y=14/5
