Hello,
Start off by distributing 25 to both x and -4
25 * X = 25x & 25 * -4 = -100
25x - 100 = 30
At this point, we add 100 to both sides so we can get 25 to be seperate from 100.
25x = 130
To get rid of the 25, divide it in both sides:
130/25 = 5.2
The answer would be 5.2
I hope this helps you with your assignment!
