Sagot :
Let x = be the number.
Using linear equations:
3x - 6 + 2 = 20
Simplify by combining like terms.
(3x) + (-6 + 2) = 20
3x - 4 = 20
Add four to left and right hand side.
3x -4 +4 = 20
3x = 24
Divide both sides by 3.
3x / 3 = 24 / 3
x = 8
So therefore, the number is 8.
Check:
8(3) - 6 + 2 = 20
24 - 6 + 2 = 20
18 + 2 = 20
20 = 20
The number is 8.

The number is 8.
The correct answer is 8.
Because here is the equation.
N x 3 - 6 + 2=20
Here is the technique.
Reverse all the action and begin from the right.So 20-2+6/3=N
So the answer is 8.
