Question

X + Y = 8
+ +
X - Y = 6
= =
13 8

Answer 1

Answer:

No solution

System of Linear Equations entered :

[1] x+y=8

[2] x-y=6

[3] x+x=13

[4] y+y=8

Equations Simplified or Rearranged :

[1] x + y = 8

[2] x - y = 6

[3] 2x = 13

[4] 2y = 8

Solve by Substitution :

// Solve equation [3] for the variable x

[3] 2x = 13

[3] x = 13/2

// Plug this in for variable x in equation [1]

[1] (13/2) + y = 8

[1] y = 3/2

[1] 2y = 3

// Plug this in for variable x in equation [2]

[2] (13/2) - y = 6

[2] - y = -1/2

[2] - 2y = -1

// Solve equation [1] for the variable y

[1] 2y = 3

[1] y = 3/2

// Plug this in for variable y in equation [2]

[2] - 2•(3/2) = -1

[2] 0 = 2 => NO solution
