Answer:


x = -2

Explanation:

If we have the equation
3x+5-13x=25, we can isolate x on one side and find it's value.

Let's combine like terms.


-10x + 5 = 25

Subtract 5 from both sides:


-10x + 5 - 5 = 25 - 5\\\\-10x = 20

Divide both sides by -10:


-10x/-10 = 20/-10\\\\x = -2

So
x = -2.

Hope this helped!
