x = - 6/11 or x = - 0.54
Step-by-step explanation:
Distribute into the parenthesis.
-5x-10-3x = 1x-4+2x
*In order to get rid of these parenthesis, multiply by an "invisible one"
Now, add or subtract the common multiples.
-8x-10 = 3x-4
Then, move the variable to one side. You do that by adding 8x to both sides, since - 8x is less than 3x.
-8x-10 = 3x-4
+8x + 8x
Once you've moved the variable to one side, add 4 to both sides.
-10 = 11x-4
+4 + 4
Then, divide both sides by 11 to isolate the variable.
-6 = 11x
11 11
This leaves you with ...
x = - 6/11 or x=-0.54
