Hello!
Answer:
The answer should have a positive sign.
Explanation:
First, you do is expand.
5(x-10)=5x-50
5x-50=30-15x
Then add by 50 both sides of an equation.
5x-50+50=30-15x+50
Simplify.
5x=-15x+80
Next add 15x both sides of an equation.
5x+15=-15x+80+15x
Simplify.
20x=80
Divide by 20 both sides of an equation.
20x/20=80/20
Simplify and solve.
80/20=4
, which is our final answer.
Hope this helps you!
Have a nice day! :)
Thanks!
