Given the statement:
You take a number, times by 5 then add 7. You get the same as if you took the number, times by 9 then add 3.
Determine the number.
Solution:
The given condition can be equated as,
5x + 7 = 9x + 3
In order to determine the number, we start first by transposing 5x and 3 to the opposite sides of the equation, hence it must be taken to note that in transposing a number, the sign changes.
5x + 7 = 9x + 3
7 - 3 = 9x - 5x
4 = 4x
Divide both sides by 4 in order to determine the value of x.
4x/4 = 4/4
x = 1
Final answer:
x =1
