Start by distributing -8 to (8-3n) and -5 to (n+1). The equation becomes:
-64+24n-5n-5=4n-1-8
Next, you can simplify both sides of the equation. It will look like:
-69-19n=4n-9
Next, add 19n to both sides so you isolate the variable on one side of the equation. You will get:
-69=23n-9
Now, you can proceed to solve this like any other two-step equation. Add 9 to both sides:
-78=23n
Divide both sides by 23:
-3.3913=n
Hope this helps!
Answer:
x = 28
Step-by-step explanation:
12/x = 3/7
Using cross products
3x = 12*7
3x = 84
Divide by 3
x = 28
that impossible cause pedro will always have more hes adding more per week and maria started 200 less and only add 25.
Answer:
Step-by-step explanation:
you divide the two to the y, which is x=3/2y
then, you simplify the second equation to y, which is -3y= -4x+12
then, you substitute the x=3/2y into the second equation,
-3y = -6+12
-3y = 6
y = -2
Substitute the y into the first equation, x= 3/2y,
x = -3
Answer: A. g+2g =352
Step-by-step explanation:
Let points : g
If molly has half of George then let
Let molly : 1
Let George: 2
Therefore g*1 =g
And g*2 = 2g
So, g+2g = 352
