  Hello ! Demi

                     I 'm Dora . I think u want to find the value of  m  from

 the given equation . 

    ur equation is

                       2m + 7  = 8

                2m  + 7 - 7 = 8 - 7 | subtract 7 from both side

                  2m   =  1

                        
[2m]
[ 2]
 =
[1 ]
[2]
      | deviding both side by 2

                           m =
[1]
[2]

 

    Clear ! Which test u r giving ? any more problem can send me private messages.  Bye . Have a great day !

        2x + y = 5      B

 -      2x - y = 3       A

              2y = 2

                y  = 1

Subs. y = 1 into B

      2x + 1 = 5

               2x= 5 -1

               2x= 4

                 x = 2

 x = 2 , y = 1

Hello u need to slove this question as follows:

2m+7=8

or,2m=8-7=1( when we transfer from one side to other its sign changes, hence +7 became -7 on changing side. ok?

or 2m=1

or m= 1/2 ( As 2 was multiplied my m on LHS so on transfering it to RHS it was divided by2.

DID U GET IT? IN CASE U DID"T U CAN PM ME.

pls note change of sign takes plaas per following rules

+ changes to --

-- changes to +

X changes to

 changes to X.
