Answer:
38+2x+125 = x+163
subtract x from both sides
38+x + 125 = 163
38+125 = 163
163+x = 163
subtract 163 from both sides
x=0
Step-by-step explanation:
Let's use the variable, x, to represent the unknown number.
We can represent the words, "the sum of a number and six, as : x + 6
The words, " 2 less than the sum", can be represented as: x + 6 - 2
The words, "the product of the number and three", can be written as: 3x
Now create an equation using "is equal to" to join the expressions:
x + 6 -2 = 3x
Now combine like terms and use inverse operations to solve for x:
x + 6 -2 = 3x
x + 4 = 3x
x + 4 - x = 3x - x
4 = 2x
4/2 = 2x/2
2 = x
The unknown number is 2

Step-by-step explanation:
The re are two cause - consequence relations inside an other one.
I use 3 different cause - consequence connectors not to mix them up.
A --> D equals “ D because A “
A --> S equals “ the reason S happens is A “
(A --> D) --> (A --> S) Equals “ if (A --> D) then (A --> S) “
