divide both sides by 2
change the signs
x= 5 is the anwer :) yay
A. Use the distributive property.
We cannot use the distribute property because there are not parentheses to distribute a number through.
5x + 15 + 2x = 24 + 4x
We can collect the terms, and isolate the variable
Adding 4 plus x for example.
This is the equation:
18 = 2(4 + x)
18 = 8 + 2x
18 - 8 = 2x
10 = 2x
10 / 2 = x
5 = x
You can analyze the equation, and than see steps that where not included.
Hope it helped,
Happy homework/ study/ exam!
B using distributive property
B) Collect variables terms on one side.
Here, the given equation is,
By Distributive property in right side,
Subtracting 8 on both sides, ( Isolating variable x )
Collect like terms,
Dividing both sides by 2 ( Isolating variable x )
Which is the solution of the given equation,
Hence, by the above explanation it is clear that we used all options except option B.
⇒ Option B would not be a step in solving 18=2(4+x).
your trying to find the variable
We don't need to use the distributive property to solve this equation. Distributive property is generally used to work out parenthesis (when solving an eqiation).
Collect like terms
Collect variable terms on one side.
Now our last step is isolating the variable (and in this case we can just do this by collecting like terms).

i dont know sorry
