Answer:
x=1
Step-by-step explanation:
To solve this question we will have to open the bracket first
So let's solve the question
5(2x-8)+15=-15
Bracket first
10x-40+15=-15
We will have to solve the question further
10x-25=-15
Add 25 to both sides
10x=10
Let's make x the subject of formula by dividing both sides by 10
x=1
Therefore x is 1
