3x+2y=7
Y=4x-2
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! ---
3x + 2y = 7
y = 4x -2
---
put the system of linear equations into standard form
---
3x + 2y = 7
4x - y = 2
---
first solve by matrix method:
---
copy and paste the above standard form linear equations in to this solver:

---
answer:
x= 1
y= 2
---
now solve by elimination:
---
3x + 2y = 7
8x - 2y = 4
---
add:
11x = 11
---
answer (same as matrix method):
x = 1
y = 2
