PLEASE HELP!!!!!!!!!! Solve this system of linear equations. Separate

Answer 1

Answer:

14.5,8.75

Step-by-step explanation:

Given equations:

             -3x = -26 -2y  ----------- i

             -11x  = 90 - 2y  --------- ii

To solve this problem, simply subtract equation ii from i;

        [-3x -(-11x)] = {-26 - 90] -[-2y - (-2y)]

             8x  = 116

                x = 14.5;

Then substitute x  = 14.5 into i to solve for y;

             -3(14.5) = -26 - 2y

               -43.5 = -26 -2y

               -43.5 + 26 = -2y

                   -17.5  = -2y

                       y = 8.75
