This problem appears to be linked with the Distributive Property. The Distributive Property allows any outside number/variable of the parenthesis to multiply with all inside numbers/variables within the parenthesis.
For example:
2(1 + 3) 2(1) + 2(3) 2 + 6 8.
With our definition, rule, and example, we are ready to solve.
4(x + 2) Multiply the outside number (4) by all inside numbers/variables (x + 2). 4(x) + 4(2) 4x + 8. If this is not solving for x, this is your answer.
If we are solving for x, we need to get 4x by itself and then simplify if possible.
4x + 8 = 0 Remember, what you do to one side of the equation you must do to the other. Subtract 8 from both sides. 4x = -8 Divide both sides by 4.
4x / 4 = x -8 / 4 = -2 X = -2
Your answers are:
4x + 8 if simplifying the expression. x = -2 if we are solving for x.
