Respuesta :
to solve this we have to work backwards.
start with -7 and add 12 to it to undo the first move
[tex] - 7 + 12 = 5[/tex]
now take 5 and multiply by 5 to undo the last move
[tex] 5\times 5 = 25[/tex]
check our work:
[tex]25 \div 5 = 5 \\ 5 - 12 = - 7[/tex]

First set and equation
{12 - 1/5x = -7}
Then solve
-1/5x = -7 - 12
-1/5x = -19
x = -19 x -5
x = 95
Check- 12 - 1/5(95)= -7
12- 19 = -7
