Question

Solve 6-k=10 by trial and error method

Answer 1

Answer:

k = -4

Step-by-step explanation:

=> 6-k = 10

→ put k = 1,

 LHS = 6 - 1 = 5

RHS = 10

LHS ≠ RHS

∴ k = 1 is not the solution.

→ Put k = 2,

LHS = 6-2 = 4

RHS = 10

LHS ≠ RHS

∴ k = 2 is not the solution

→ put k = 3,

LHS = 6-3 = 3

RHS = 10

LHS ≠ RHS

∴ k = 3 is not the solution.

→ Put k = 4,

LHS = 6-4 = 2

RHS = 10

LHS ≠ RHS

∴ k = 4 is not the solution

→ put k = -2,

LHS = 6-(-2) = 8

RHS = 10

LHS ≠ RHS

∴ k = -2 is not solution.

→ put k = -4,

LHS = 6-(-4) = 6+4 = 10

RHS = 10

LHS = RHS

∴ k = -4 is the solution.
