x = your number
When 12 is subtracted from a number, the result is equal to 25 added to twice the number means:
x - 12 = 2 x + 25
Subtract x to both sides
- 12 = x + 25
Subtract 25 to both sides
- 37 = x
x = - 37
Check results:
x - 12 = 2 x + 25
- 37 - 12 = 2 ∙ ( - 37 ) + 25
- 49 = - 74 + 25
- 49 = - 49

Let the number be x
X_12=2x+25
Subtract x to both sides
-12=x+25
Subtract 25 to both sides
-37=x
X=-37
; X-12=2x+25
-37 -12=2(-37)+25
-49=-74+25
-49=-49
X_12=2x+25
Subtract x to both sides
-12=x+25
Subtract 25 to both sides
-37=x
X=-37
; X-12=2x+25
-37 -12=2(-37)+25
-49=-74+25
-49=-49
