If you would like to simplify 4 * (n + 5), you can do this using the following step:
4 * (n + 5) = 4 * n + 4 * 5 = 4 * n + 20
The correct result is 4 * n + 20.
So k=1000 like 4k=4 000 so 6/7 of a thousnad =0.857142857 so times 6=0.857142857
Multiply the first equation by 2
2x + 2y =30
now we’ll add the second equation to the first equation
2x + 2y =30
-2x+5y= -2
7y=28
divide by 7
y=4
now plug y back into the first equation
x + 4 = 15
subtract 4
x=11
The answer is 5,180! I used a calculator
