Answer:

(8, -1)

Step-by-step explanation:

Next time, please separate the two equations, as with a comma or semicolon:

-3x=-26-2y; -11x=-90-2y

Note that bothe quations end in -2y.  Solve both for -2y and then equate the results:

-3x + 26 = -2y; -11x + 90 = -2y

Then -3x + 26 = -11x + 90

Grouping like terms together, we get -3x + 11x = 90 - 26, or

8x = 64

Then x = 64/8 = 8.

Substitute 8 for x in either of the given equations, to find y:

-3(8) = -26 - 2y

-24 + 26 = -2y

2 = -2y, and so y = -1.

The solution is (8, -1).
