Answer:
x = -7
Step-by-step explanation:
5(x-2)=3x+4(x+1)
First, multiply the 5 with the x and the 5 with the -2. You are using the distributive property.
5x -10 = 3x + 4 (x+1)
Then multiply the 4 with the x and the 4 with the 1 on the other side. Again, you are using the distributive property.
5x-10=3x+4x+4
Next, combine like terms. So you're going to combine the 3x and the 4x on the right side.
5x-10=7x+4
Then, subtract 5x from both sides. Also, subtract the 4 from both sides. You do this in order to get all of the x's on one side of the equation.
-14 = 2x
Finally, divide 2 from both sides. You do this because right now, the equation says 2 times x, and you need to get the x alone.
-7 = x
You are finished
Answer:
No, not necessarily
Step-by-step explanation:
When you subtract 3x to the other side you dont want to forget abt that other number, since 1 is a positive it is going to be a + 1
the correct answer is C
y = -3x + 1

Put 53/x = k/2hours I think the equation is something like that
Consider the below figure attached with this question.
Given:

To find:
The number of line that represents the solution of given inequality.
Solution:
We have,

Subtracting 6 from both sides, we get


If an inequality is multiplied or divide by a negative number, then the sign of inequality must be change.
Divide both sides by -4.


The value of x is less than -3. It means number of the left of -3 are included in the solution set but -3 is not included in the solution set.
So, there is an open circle at x=-3 on the number and an arrow from -3 towards left.
Therefore, the correct option is A.
