-26x - 5 = x - 56
That should be the equation that is formed.
If you are attempting to find said number (x), then follow these steps:
First, add five to both sides:
-26x = x - 51
Then subtract x from both sides to get the variable on one side of the equation:
-27 x = -51
Now, divide both sides by -27, which will get you the final answer of:
x = -1.9 (rounded up)
Hope this helps!
