Question

solve the eqn of x +5= 12 by using trial and error method in the table​

Answer 1

Answer:

let we choose x = 1

so 1+ 5 = 6

which is not a solution

let we choose x = 2

so 2 + 5 = 7

which is not a solution

let we choose x = 3

so 3 + 5 = 8

which is not a solution

let we choose x = 4

so 4 + 5 = 9

which is not a solution

let we choose x = 5

so 5 + 5 = 10

which is not a solution

let we choose x = 6

so 6 + 5 = 11

which is not a solution

let we choose x = 7

so 7 + 5 = 12

which is a solution

So x = 7

Answer 2

Answer:

x LHS = 2x + 16 RHS = 26

1 2x + 16 = 2×1 + 16 = 18 26

2 2x + 16 = 2×2 + 16 = 20 26

3 2x + 16 = 2×3 + 16 = 22 26

4 2x + 16 = 2×4 + 16 = 24 26

5 2x + 16 = 2×5 + 16 = 26 26

Here, LHS = RHS for x = 5 is the solution.
