Solve each equation. Record your work and check your solution B. -6x-7=-1(-9+2x)

x = -4

Step-by-step explanation:

So we start with the equation -6x - 7 = -1(-9 + 2x)

Then we distribute the -1 to the -9 and the 2x so we get:  -6x - 7 = 9 - 2x

Now we make the x-values on one side and the numbers on the other side like this:  

-6x + 6x - 7 - 9 = 9 - 2x + 6x - 9

-16 = 4x

Now we divide 4 / -16 which gives us x = -4

-16/4 = 4x/4

x = -4

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
