Notice how on both sides of the equation there is one coefficient (number being multiplied by x) and a constant (just a plain number). You want all constants to be on one side and all coefficients on the other. He’s how do to that:
2x+14=-21-5
I am choosing that all constants will be on the right side, so I will do the inverse operation of any constant on the left side to remove it. Here, a constant on the left side is 14. I will subtract 14 from both sides of the equation. Positive 14 minus 14 is zero, so it cancels out and removes it.
2x+14-14 = -21-5x
2x = -35-5x
See how the 14 is now gone? The equation looks much simpler now. Okay next, you can see that there is a coefficient on the “constant side” that I’ve chosen, so I am going to remove that. Negative 5 plus positive 5 equals zero. Do this on both sides of the equation.
2x+5x = -35-5x+5x
7x = -35
Now the equation is just two numbers. All that is left to do is divide by the last coefficient, 7, in this case.
7x/7 = -35/7
x = -5

Answer:

Step-by-step explanation:

solve for x

2x+14=-21-5

2x+14=-26

subtract 14 from both sides

2x+(14-14)=-14-26

2x=-14-26

2x=-40

divide both sides of 2x = -40 by 2

\frac{2x}{2} =\frac{-40}{2}

2/2=1

x=\frac{-40}{2}

x= -20

−k−(−8k+7) what is the answer, I want an explanation please
lord [1]

Answer:

Step-by-step explanation:

-k - ( -8k + 7)

negative sign is outside the parenthesis. so it should be multiplied with -8k and 7

-k - (-8k + 7) = -k - 8k * (-1) + 7*(-1)

                    = -1k + 8k - 7

Now -k and 8k are like terms. So, combine them.

                    = 7k - 7
