b
a and d should not be considered bc it is not logically correct. c is eliminated because that may not always be the case. therefore it should be b.
Ight bet I’ll see what I can do
<em><u>Answer: x=-2 *The answer should be the negative sign.*</u></em>
Step-by-step explanation:
distributive property: a(b+c)=ab+ac
remove parenthesis
-15x-15*4=-30
15*4=60
-15x-60=-30
add 60 both sides of an equation.
-15x-60+60=-30+60
simplify.
-15x=30
divide by -15 both sides of an equation.
-15x/-15=30/-15
simplify.
30/15=2
x=-2
Hope this helps!
Thanks!
Have a great day!
