Answer:
x= -2
Step-by-step explanation:
-0.2(25x+5)-5 = 4
We move all terms to the left:
-0.2(25x+5)-5-(4) = 0
We add all the numbers together, and all the variables
-0.2(25x+5)-9 = 0
We multiply parentheses
-5x-1-9 = 0
We add all the numbers together, and all the variables
-5x-10 = 0
We move all terms containing x to the left, all other terms to the right
-5x= 10
x= 10/-5
x= -2
