Given the statement:
3 less than 2 times a number is 5
Determine the number.
Solution:
The given numerical statement can be written as,
3 - 2x = 5
To find for the number, we solve for x. The first step is to transpose -2x and 5 to the opposite sides of the equation, hence in transposing a number, the sign changes.
2x =3 - 5
2x = -2
Divide both sides by 2 in order to cancel out 2x, leaving behind x.
2x/2 = -2/2
x = -1
Final answer:
x =-1
