To solve for the value of x in the equation x - 5 = -6, we need to isolate the variable x on one side of the equation. One way to do this is by multiplying both sides of the equation by -1.
So, both sides of the equation x - 5 = -6 should be multiplied by -1 to solve for the value of x.

what is the answer
When both sides of the equation x - 5 = -6 are multiplied by -1, we get:
-1(x - 5) = -1(-6)
-1x + 5 = 6
Simplifying further:
-x + 5 = 6
To solve for x, we can subtract 5 from both sides of the equation:
-x + 5 - 5 = 6 - 5
-x = 1
Finally, multiplying both sides of the equation by -1 gives us the value of x:
(-1)(-x) = (-1)(1)
x = -1
So, the value of x in the equation x - 5 = -6 is x = -1.
-1(x - 5) = -1(-6)
-1x + 5 = 6
Simplifying further:
-x + 5 = 6
To solve for x, we can subtract 5 from both sides of the equation:
-x + 5 - 5 = 6 - 5
-x = 1
Finally, multiplying both sides of the equation by -1 gives us the value of x:
(-1)(-x) = (-1)(1)
x = -1
So, the value of x in the equation x - 5 = -6 is x = -1.

?(1 point)
If 2x = -4, we can solve for x by dividing both sides of the equation by 2:
2x/2 = -4/2
x = -2
Now, to find the value of 8x, we substitute the value of x back into the expression:
8x = 8(-2)
8x = -16
So, the value of 8x is -16.
2x/2 = -4/2
x = -2
Now, to find the value of 8x, we substitute the value of x back into the expression:
8x = 8(-2)
8x = -16
So, the value of 8x is -16.
