Given the numerical equation:
120 ( 2x - 2 ) = 240
Solve for x.
Solution:
In order to solve for x, we simply need to distribute first120 to each value inside the parenthesis.
120(2x - 2) = 240
240x -240= 240
transpose -240 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
240x = 240 + 240
240x = 480
Divide both sides by 240, in order to cancel out 240x, leaving behind x.
240x/240 = 480/240
x = 2
Final answer:
x = 2
