Question

-4x-10y=-2
4x+ 3y=-5

Answer 1

(3, 1)

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).

Answer 2

My work is shown up above in the picture.

Answer : (-2,1)

My answer is definitely right. I checked my answers by using x and y into the two equations. In other words using the substitution method.
