-12+x=50

To solve we need to get x by itself. Therefore add 12 to both sides:

+12 -12 +x = 50 +12

`therefore x= 62`

To check, substitute this value into the original equation:

-12 + (62) = 50

50 = 50

`therefore` x=62 is correct.

-12+x=50

 To solve: 
  • Rewrite: x+(-12)=50
  • Simplify: x-12=50
  • Since it is subtraction, what is the opposite operation for it? (addition) -- Add 12 on both sides to isolate 'x': x-12+12=50+12
  • Simplify: x=62
To check: 
  • Plug 62 in for 'x' in the original equ: -12+62=50
  • Solve -12+62. 
  • Since -12+62 is 50, the statement is true. 
  • 50=50

-12 + x = 50

To solve this , first add 12 on both sides

By adding 12 on both sides , you should get

x = 62 which is your answer for " x " 

Now to check : 

Plug in 62 as " x "

-12 + 62 = 50  subtract -12 with 62

50 = 50
