If you would like to solve the equation -5x - 25 = 78, you should do this using the following steps:
<span>-5x - 25 = 78
</span>-5x - 25 + 25 = 78 + 25
-5x + 0 = 103
-5x = 103 /(-5)
x = 103 / (-5)
x = - 103/5 = - 20.6
The error was already made at step 1.
ANSWER: x = 130°
EXPLANATION: You must add given angles and then subtract from 180°.
