Question

3x-2x=3
by trail and error method

Answer 1

Answer:

The value of $x$ for $3x-2x=3$ is 3

Step-by-step explanation:

Given equation  $3x-2x=3$ we need to solve this by trial and error method

  Trial and error is a fundamental method of problem-solving. Repeating varies attempts until to get correct solution  

take  LHS  $3x-2x$

         $x=0$   ⇒  $3x-2x$⇒ 3(0)-2(0)=0 $\neq$ 3

                       $x=1$ ⇒ 3(1)- 2(1) = 3-2= 1   $\neq$ 3

                       $x=2$ ⇒   3(2)-2(2)= 6-4= 2 $\neq$3    

                       $x= 3$ ⇒ 3(3)-2(3)= 9-6 = 3 =3  

                          for $3x-2x=3$ is 3
