37 is your answer

Step-by-step explanation:

let "a number" = x

"twelve subtracted from [x]" = x - 12

"equals 25" = = 25

Set the equation

x - 12 = 25

Isolate the variable. Note the equal sign, what you do to one side, you do to the other. Add 12 to both sides

x - 12 (+12) = 25 (+12)

x = 25 + 12

x = 37
