answer;
x=0
Step-by-step explanation:
4 + 2 (x + 3x) = 4 - x(2-3) + 2x
let remove d brackets
4 + 2x + 6x = 4 - 2x + 3x + 2x
llet collect like terms
2x + 6x - 3x -2x + 2x = 4-4
5x = 0
x = 0
Answer: Last option.
Step-by-step explanation:
Given the expression:

The Quotient of powers property states that:
And the Power of a powet property states that:
Then, applying these properties, you get:

Now you must remember that:
Therefore, simpliying the expression, you get:

Answer:
y = 3/2
Step-by-step explanation:
5(2y - 1) - 2(3y) = 1
First we use distributive property:
10y - 5 - 6y = 1
because 5 × 2y = 10y
and -2 × 3y = -6y
Now we combine the like terms:
4y -5 = 1
because 10y - 6y = 4y
Now we have to send the -5 to the other side. (when we send it to the other side it becomes positive because right now it is negative)
4y = 1 + 5
Again we combine the like terms:
4y = 6
(because 5 + 1 = 6)
Now we have to send the 4 to the other side because we need to get the y value. (when we send it to the other sidr it will be divided)
y = 6/4
and we simplify:
y = 3/2
And we cannot simplify or do anything else. So that is the answer.
Hope that helped!
