Let 'x' be the nunber.
Since number decreased by 30 means x - 30
14 decreased by 3 times the number means 14-3x
Since these are same,
x-30=14-3x
x+3x = 14+30
4x = 44
x = 11
Since number decreased by 30 means x - 30
14 decreased by 3 times the number means 14-3x
Since these are same,
x-30=14-3x
x+3x = 14+30
4x = 44
x = 11
-
x-30=14-3x
4x=44
x=11
4x=44
x=11

In algebra (because it is shorter), let x be the number:
x-30 = 14-3x
Add 3x to the equation (gets the x's on one side)
4x-30=14
add 30 to the equation (leaves only x's on lhs of the equation)
4x=44
divide by 4
x=11
x-30 = 14-3x
Add 3x to the equation (gets the x's on one side)
4x-30=14
add 30 to the equation (leaves only x's on lhs of the equation)
4x=44
divide by 4
x=11

Let x be the number.
x - 30 = 14 - 3x
x + 3x = 14 + 30
4x = 44
x = 44/4 = 11
x - 30 = 14 - 3x
x + 3x = 14 + 30
4x = 44
x = 44/4 = 11
-
x=11

Let the number be x:
x - 30 = 14 - 3x
add 30 to both sides, add 3x to both sides:
4x = 44
divide both sides by 4:
x = 44/4 = 11
- .--
x - 30 = 14 - 3x
add 30 to both sides, add 3x to both sides:
4x = 44
divide both sides by 4:
x = 44/4 = 11

First write and solve the equation.... considering x the number the equation is so
x - 30 = 14 -3x ==> 4x = 44 ==> x= 11 OK!
x - 30 = 14 -3x ==> 4x = 44 ==> x= 11 OK!
-
x - 30 = 14 - 3x
4x = 44
x = 11
Number is 11
4x = 44
x = 11
Number is 11
-
x - 30 = 14 - 3x
4x = 44
x = 11.
4x = 44
x = 11.
