If six less than twice a number, x, is 38, then the value of x will be 21
Let the unknown number be x
Twice the number x is expressed as 2x
six less than twice a number, x will be expressed as 2x - 6
If the result is equal to 36, this will be written as 2x - 6 = 36
Solve the resulting equation
2x - 6 = 36
Add 6 to both sides
2x - 6 + 6 = 36 + 6
2x = 42
x = 42/2
x = 21
Hence if six less than twice a number, x, is 38, then the value of x will be 21.
