Hint: We first assume the number as and find the algebraic expression of the given conditions separately where two less than 4 times the number is the same as the number plus 34. We solve the equation and find the value of the variable.
Complete step-by-step solution:
We assume the number to be .
It is given that two less than 4 times a number is the same as the number plus 34.
We separately form the algebraic expression of the given conditions.
We first take the Two less than 4 times the number .
This gives .
Now we take the number plus 34 which is equal to .
As they are equal, we get .
We now solve the expression to get
The number is 12.
Note: We need to be careful about the back calculation process to verify the solution.
From Two less than 4 times the number 12, we get .
From the number plus 34, we get .
The condition satisfies the answer and also verifies it.
