Question

write four solutions of an a equation 2x+2y = 2​

Answer 1

Answer:

Answer

Given equation is:

2x+y=7

For x = - 1, we get

−2+y=7

⇒y=9

∴ (-1, 9) is a solution.

For x = 0, we get

⇒0+y=7

⇒y=7

∴ (0, 7) is a solution.

For x = 1, we get

⇒2+y=7

⇒y=5

∴ (1, 5) is a solution.

For x = 2, we get

⇒4+y=7

⇒y=3

∴ (2, 3) is a solution.

Hence, we have four solution (−1,9),(0,7),(1,5)and(2,3)

Hope it helps!!!

Answer 2

Answer:

2x-2y=2 -------->(i)

2x=2+2y

x = 2+2y/2 ----------> (ii)

from equation (i) and (ii)

2[2+2y/2] - 2y = 2

4 + 4y - 2y = 2

4 + 2y = 2

2y = 2 - 4

2y = -2

y = -2/2

y = -1

Now, Put the value of y in equation (ii)

x = 2+2(-1)/2

x = 2-2/2

x = 0/2

x = 0

Therefore,

x = 0 and y = -1
