Question

2x+y =–3
x–y=–3
please answer ​

Answer 1

Answer:

First Step,

simply add the two equations, which will result as

• 3x = -6
• x= -6/3 = -2
• x=(-2)

put value of x in any equation (I'm putting value of x in equation no. 2)

• -2-y = -3
• y = 1

x= -2, y= 1

Note: you can verify the answer by putting the values of x and y in any of the two equations

Answer 2

Answer:

x=-2

y=1

Step-by-step explanation:

2x+y=-3 --------------------------------------------(i)

x-y=-3 ----------------------------------------------(ii)

Now From equation 2,

Find the value of x which is -3+y

Therefore x=-3+y ------------------------------ (iii)

Now putting the value of x in equation 1 we get,

y=1

Now putting the value of x in equation 3 we get,

x=-2

Thus x=-2 and y=1
