Answer:
n= 4
Step-by-step explanation:
3 multiplied by n is 3n.
3 multiplied by -5 is -15.
so 3n-15= 7-2(n+1)
7-2(n+1) is -2 multiplied by n is -2n and -2 multiplied by 1 is -2.
3n-15=7-2n-2
then move the variables to one side and numbers to the one side.
3n+2n=15+7-2
*If you are moving across the equation the symbols change. Like negative to positive. Division to multiplication.
so 5n=22-2
5n=20
5 multiplied by 4 is 20 so n is going to be 4.
N=4
Answer:
add x
Step-by-step explanation:
The operation "subtract 5" has eliminated the constant from the right side of the equation, so the next step would be to eliminate the variable from the left side. You do that by adding the opposite of the variable term.
The opposite of the term -x is x, so we "add x" as the next step.
This makes the solution look like ...
-x +6 = 5 -3x
-x +1 = -3x . . . . . . subtract 5
1 = -2x . . . . . . . . . add x
-1/2 = x . . . . . . . . .divide by -2

<em>Comment on this solution</em>
My preference is always to add the opposite of the variable term with the smallest coefficient. Here, that term is -3x, so I would add 3x as a first step. This leaves the only x-term with a <em>positive</em> coefficient, so can reduce errors in the solution.
Answer:
The answer should be x < 
Step-by-step explanation:
Answer: ⇒ <u><em>=368</em></u>
Step-by-step explanation: ⇒ Multiply by the numbers. Product it's going to be multiply by the numbers, fractions, multiples, and factors. You can also remove parenthesis, this give us, 92*4=368. Hope this helps! Thanks!
T he x and y intercepts of the equation: 
are : y-intercept is (0,-5) and x-intercept is (4,0)
So, Option D is correct.
Step-by-step explanation:
we need to identify the x and y intercepts of the equation:
Finding x-intercept
For finding x-intercept put y=0
We are given the equation:
Solving:
So, x-intercept is (4,0)
Finding y-intercept
For finding y-intercept put x=0
We are given the equation:
Solving:
So, y-intercept is (0,-5)
the x and y intercepts of the equation: are :y-intercept is (0,-5) and x-intercept is (4,0)
So, Option D is correct.
