Answer:
x = -5
Explanation:
Start by adding the 5x to each side of the equation to the left to get...
-25 = 5x + 25 + 5x
Then you would add 25 to each side of the equation to get...
0 = 10x + 25 + 25
Adding on, you would simplify this step to get...
0 = 10x +50
You would now have to make the x variable on one side alone so you would subtract 50 from both sides of the equation again to get...
-50 = 10x
Finally you would divide both sides of the equation by 10 to get x alone...
-50/10 = 10x/10
And simplify that to get...
x = -5
