Question 759645: Solve the system of equations and give the value of x:
3x + 12y = 9
x = -4y - 3
Please show details thank you so much. Answer by oscargut(2103) (Show Source):
You can put this solution on YOUR website! 3x + 12y = 9
x = -4y - 3
Then:
3x + 12y = 9
x +4y = -3
If we multiply the 2nd equation by -3 we have :
3x + 12y = 9
-3x -12y = 9
Adding them:
0x+0y = 18 (not true)
Answer: The system has no solution
