-2x+7y &= 10
3x+7y &= 2
Answer
What is the result of adding these two equations?

2x+7y &= 4
-2x-8y &= -2
Answer

This can be rewritten as:

-2x + y - (-7x + 3y) = 0 - 2
-2x + y + 7x - 3y = - 2
5x - 2y = -2

So, the result of subtracting the two equations is:

5x - 2y = -2

Subtracting the second equation from the first (equation 1 - equation 2) gives:

(-2x + 7y) - (3x + 7y) = 10 - 2
-2x + 7y - 3x - 7y = 8
-5x = 8

Therefore, the result of subtracting the second equation from the first is:

-5x = 8

Adding the two equations together gives:

(2x + 7y) + (-2x - 8y) = 4 + (-2)
2x + 7y - 2x - 8y = 2
-x - y = 2

Therefore, the result of adding the two equations is:

-x - y = 2

Adding the two equations together gives:

(5x - 9y) + (-7x + 2y) = 1 + (-5)
5x - 9y - 7x + 2y = -4
-2x - 7y = -4

Therefore, the result of adding the two equations is:

-2x - 7y = -4
