Question

2m-8=6m-4solve the following equation by systematic method and check the answer​

Answer 1

Answer:

m=-2

Step-by-step explanation:

2m-8=6m

6m=2m-8

6m-2m=-8

4m=-8

m=-8÷4

m=-2

Answer 2

Answer:

=> The value of m is -1, and it satisfies the expression.

Step-by-step explanation:

Given that:-

$2m-8=6m-4$

To find:- The value of the expression, and also we have to check that the value of m satisfies the expression or not,

To solve this expression, we have to use the transposition method:  

As we have,

=> $2m-8=6m-4$

Add both sides by $8$,

=> $2m-8+8=6m-4+8$

Simplifying it further, we get

=> $2m = 6m +4$

Subtract both sides by $6m$,

=> $2m -6m= 6m +4-6m$

=> $-4m = 4$

Divide both sides by $-4$,

=> $m = -1$

Hence, the required solution is -1.

Checking:-

=> $2m-8=6m-4$

=> 2 ( -1 ) - 8 = 6 ( -1 ) - 4

=> -10 = -10

LHS = RHS
