a+c=-10;b-c=15;a-2b+c=-5 No solution System of Linear Equations entered : [1] 2a+c=-10
[2] b-c=15
[3] a-2b+c=-5
Equations Simplified or Rearranged :
[1] 2a + c = -10
[2] - c + b = 15
[3] a + c - 2b = -5
Solve by Substitution :
// Solve equation [3] for the variable c
[3] c = -a + 2b - 5
// Plug this in for variable c in equation [1]
[1] 2a + (-a +2?-5) = -10
[1] a = -5
// Plug this in for variable c in equation [2]
[2] - (-? +2b-5) + b = 15
[2] - b = 10
// Solve equation [2] for the variable ?
[2] ? = b + 10
// Plug this in for variable ? in equation [1]
[1] (? +10) = -5
[1] 0 = -15 => NO solution
No solution
