Using elimination method Solve this simultaneous equation.
14+2e =5d
d = 5e-12
Answers
Answer:
Step-by-step explanation:
System of Linear Equations entered :
[1] 5d-2e+14=0
[2] 5e=d+12
Equations Simplified or Rearranged :
[1] 5d - 2e = -14
[2] -d + 5e = 12
Graphic Representation of the Equations :
-2e + 5d = -14 5e - d = 12
Solve by Substitution :
// Solve equation [2] for the variable d
[2] d = 5e - 12
// Plug this in for variable d in equation [1]
[1] 5•(5e-12) - 2e = -14
[1] 23e = 46
// Solve equation [1] for the variable e
[1] 23e = 46
[1] e = 2
// By now we know this much :
d = 5e-12
e = 2
// Use the e value to solve for d
d = 5(2)-12 = -2
Solution :
{d,e} = {-2,2}
