a=-2
Step-by-step explanation:
Combine common variables on both sides.
3a-7a-28=10a
-4a-28=10a
Add variables to other side
-28=14a
Divide each side by 14
a=-2
Answer:
I believe they are not.
Step-by-step explanation:
The reason for this is that in the first algebraic expression there are parentheses which means you must do anything inside the parentheses first. On the other hand, the second expression doesn't have parentheses so you'll end up subtracting 3 from x, also not 100% sure!!
Answer:
there are 3 terms
Step-by-step explanation:
Hope i helped :)
If the number is x, then 2*(x+3)-7=9 due to that you subtract the result of double of x+3. Adding 7 to both sides, we get 2*(x+3)=16. Next, we divide both sides by 2 to get x+3=8 and subtract 3 from both sides for our final result, x=5
Answer:
d=6
Step-by-step explanation:
subtract 5 from both sides
then simplify what you get
then divide both sides by 4
then simplify to get answer
