Solve the system of equations using either the substitution method or the multiplication/addition method
using his given
3x+2y=14
2x-4y=4

6x+4y=28
2x-4y=4
8x = 32
x = 4
2y = 14 - 12 = 2
y = 1
(x , y) = (4 , 1)

question: how can check your solution by writing the system as a matrix equation and using the inverse matrix? .
