Question

What is the value of x in -5x-(-7-4x)-2(3x-4)

Answer 1

Answer:

x = 1

Step-by-step explanation:

-5x-(-7-4x)-2(3x-4)

-5x + 7 - 4x - 6x + 8          First step is to factor all the numbers out so you have          no parenthesis. In this case -(-7 just turns into + 7 because two negatives equal a positive. As well as -2*3x and -2*-4 which gives you -6x + 8.

-15x + 15                            In this step you combine like terms.

-15x = -15                            Next you move the whole number to the other side of the equation by subtracting it from both sides.

x = 1                                     Finally you divide -15 by -15 to get x by its self.
