-10 + x + 4 - 5 = 7x - 5
-x -x
-10 + 4 - 5 = 6x - 5
-6 - 5 = 6x - 5
-11 = 6x - 5
+5 + 5
-6 = 6x

To solve this equation, you must get the variable (in this case x) on only one side of the equation.

First, we will combine like terms on the left side of the equation to simplify it.

-10+4-5 = -11. So, we can rewrite this equation as x-11=7x-5

Next, you should subtract x from both sides, so that there is only one variable, and it is on the right side of the equation.

So, the resulting equation is -11=6x-5. Then, you have to add 5 to both sides, so that you can get the 6x alone.

So, the resulting equation is -6=6x

To undo the multiplication caused by the coefficient, you have to divide both sides by 6, to get your final answer of x= -1
