Question

which is the solutions to the system of equations shown { 3x - y = 6 and here is the other equation{ x - 2y = -18

Answer 1

(6, 12)

Explanation:

{ 3x - y = 6

{ x - 2y = -18

by using elimination:

6x -2y=12

x - 2y= -18

________-

5x = 30

x = 6

y = 18-6 = 12

the solutions = {(6, 12)}
