Question

solve 5x +2 = 27 by trial and error method ​

Answer 1

Answer:

x=5

Step-by-step explanation:

i) Putting x=1:

    5(1) +2 ≠ 27

=> 5+2 ≠27

=> 7 ≠27

Hence, x = 1 is not the solution for this equation

ii) Putting x=2:

    5(2) +2 ≠ 27

=> 10+2 ≠27

=> 12 ≠27

Hence, x = 2 is not the solution for this equation

iii) Putting x=3:

    5(3) +2 ≠ 27

=> 15+2 ≠27

=> 17 ≠27

Hence, x = 3 is not the solution for this equation

iv) Putting x=4:

    5(4) +2 ≠ 27

=> 20+2 ≠27

=>22 ≠27

Hence, x = 4 is not the solution for this equation

v) Putting x=5:

    5(5) +2 = 27

=> 25+2 = 27

=> 27 = 27

Hence, x = 5 is the solution for this equation.
