Answer:
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
