Equations - simple

Solve the system of linear equations:

x-2y=6
3x+2y=4

Final Answer:

x =  2.5
y =  -1.75

Step-by-step explanation:

x−2y=6 3x+2y=4  x−2⋅ y=6 3⋅ x+2⋅ y=4  x−2y=6 3x+2y=4  Pivot:Row1↔Row2 3x+2y=4 x−2y=6  Row2−31​⋅ Row1→Row2 3x+2y=4 −2.67y=4.67  y=−2.666666674.66666667​=−1.75 x=34−2y​=34−2⋅ (−1.75)​=2.5  x=25​=2.5 y=4−7​=−1.75
