Question

calculate x-2y= 5 and 3x-6y = 15 algebraically

Answer 1

Answer:

we have x - 2y = 5 and 3x - 6y = 15

Now, x - 2y = 5

= x = 2y + 5

When y = -1 then, x = 3

When y = 0 then, x = 5

Thus, we have the following table giving points on the line x - 2y = 5

X 3 5

Y 1 0

Now, 3x - 6y = 15

When y = -2, then x = 1

When y = -3, then x = -1

Thus, we have the following table giving points on the line 3x - 6y = 15

X 1 -1

Y -2 -3
