Answer: x=-2 *The answer should be the negative sign.*
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!
Answer:
Step-by-step explanation:
[tex]\sf -15x+15(-4)=-30[/tex]
[tex]\sf -15x-15\times \:4=-30[/tex]
[tex]\sf -15x-60=-30[/tex]
[tex]\sf -15x-60+60=-30+60[/tex]
[tex]\sf -15x=30[/tex]
[tex]\sf \cfrac{-15x}{-15}=\cfrac{30}{-15}[/tex]
[tex]\sf x=-2[/tex]
