Answer:
4 1/5
Step-by-step explanation:
25=5x+4.
We move all terms to the left:
25-(5x+4.)=0
We add all the numbers together, and all the variables
-(5x+4)+25=0
We get rid of parentheses
-5x-4+25=0
We add all the numbers together, and all the variables
-5x+21=0
We move all terms containing x to the left, all other terms to the right
-5x=-21
x=-21/-5
x=4+1/5
