Given the statement:
3 less than 5 times a number is 4 less than that same number
Determine the value of the number.
Solution:
In order to determine the value of the number, we must first represent the given.
5x - 3 = x - 4
In order to solve for x, we transpose -3 and x to the opposite sides of the equation, hence it must be taken to note that in transposing a number, the sign changes.
5x - x = -4 + 3
4x = -1
Divide both sides by 4 in order to determine the value of x.
4x/4 = -¼
x = -¼
Final answer:
x = -¼
