Question

From the sum of 3x–y = 11 and –y-11 , subtract 3x–y–11.​

Answer 1

Answer:

first sum of the 3X-y =11 and -y-11

Step-by-step explanation:

3x-y= 11 plus -y-11

arranging 3x-y-y-11 =11

• 3x- 2y = 11+11
• 3x -2y = 22. equation (1)

now subtract 3x-y-11 we will get

• ( 3x -2y) -(3x-y-11) = 22
• 3x-2y -3x +y +11 =22

by arrangements

• 3x-3x -2y +y = 22- 11
• 0- y = 11
• or y = -11

Answer 2

Step-by-step explanation:

3x-y=11.

3x-y-11+(-y-11) ( sum of 3x-y=11 and -y-11)

3x-y-11-y-11

3x-2y-22

3x-2y-22-(3x-y-11)

3x-2y-22-3x+y+11

=-y-11=0

y=-11
