Answer:
Let the number be x
if we multiply it by 3 the number becomes 3x
it is given that 2 is subtracted from the number
so required equation = 3x-2 .............(equ. 1)
the number becomes 10 more than twice so = 10+2x .............(equ. 2)
equating both equations 1 and 2
3x -2 = 10 + 2x
3x - 2x = 10 + 2
x = 12
So I am a number whose value is 12.
