Х-у=5 х+у=7

To solve this system of equations, we can use the method of elimination.

Adding the two equations together, we get:

(х - у) + (х + у) = 5 + 7 2х = 12

Dividing both sides of the equation by 2, we find:

х = 6

Substituting this value of х into one of the original equations, we have:

6 + у = 7

Simplifying, we find:

у = 1

Therefore, the solution to the system of equations is х = 6 and у = 1.
