Answer:
Answer is : 0
NO solution
Explanation:
System of Linear Equations entered :
[1] y + 3x = 7
[2] y + 3x = -6
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = -3x - 6
// Plug this in for variable y in equation [1]
[1] (-3x-6) + 3x = 7
[1] 0 = 13 => NO solution
No solution
