What are the exact steps of solving one unknown using addition and multiplication principles?
2(3x - 1) + 4x - 14
This is what you do;
You evaluate what is enclosed in brackets first and any multiplication or division attached to it.
With the example above you values in the brackets by 2
(2 x 3x) - (2 x 1)
Append the second part on the expression
Group like terms together
6x + 4x - 2 - 14
Therefore the simplest form of the expression is 10x -16
Note that If there is an equal sign at the end of the expression then you would move the -16 to the other side of the equal sign where it becomes 16 (Positive)
Move -16 to the other side
10x=16 + 4
Divide both sides by the coefficient of x
