Question

Solve the following equations by trial and error method. 3x - 11= 1​

Answer 1

Answer:

x = 4

Step-by-step explanation:

let x=4

so 3×4-11 = 12-11 = 1

since, RHS = LHS

x = 4

Answer 2

Answer:

x = 4

Step-by-step explanation:

Solving by Trial and Error

CASE 1 :  x = 1

3 x (1) - 11 = 1

3  - 11 $\neq$ 1

CASE 2 :  x = 2

3 x (2) - 11 = 1

6  - 11 $\neq$ 1

CASE 3 :  x = 3

3 x (3) - 11 = 1

9  - 11 $\neq$ 1

CASE 4 :  x = 4

3 x (4) - 11 = 1

12 - 11 = 1
