Answer:

(3, 1)

Step-by-step explanation:

Next time, please include the directions:  "Find the solution of the system of linear equations using linear combinations:

-4x-10y=-2

4x+ 3y= -5

----------------

      -7y = -7, so y = 1.  If y = 1, then -4x - 10y = -2 becomes

-4x - 10(1) = -2, or

-4x + 10 = -2, or

-4x = -12.  Then x must be +3.

The solution to this system of linear equations is (3, 1).
