Question

use substitution to solve system of equation
x-2y=12
Y = 3x + 14​

Answer 1

The answer is x=-8 and y=-10

Answer 2

Answer:

x = -6, y= -4

Step-by-step explanation:

y = 3x + 14

x - 2y = 12                                Y = 3x + 14

x - 2 ( 3x + 14 ) = 12                 Y = 3 (-6) + 14      

x -6x -28 = 12                          Y = -18 + 14                                    

-5x - 28 = 12                            Y = -4                              

-5x = 30

x = -6
