Answer:
Step-by-step explanation:
First, you need to simplify step-by-step:
6x−24x+13
=6x+−24x+13
Now, you combine like terms:
=6x+−24x+13
=(6x+−24x)+(13)
=−18x+13
That's how you get your answer:
=−18x+13
8*(n+6)=80
distribute
8n+48 = 80
subtract 48 from each side
8n = 32
divide by 8
n=4
You need to find opposite terms when using the elimination method to solve a system of equations so that way you can find out the y or the x after you have crossed out the fraternal twins. You have to get rid of either the y or x in order to work it out and find the y or x value.
X = length
2x + 2(x + 105) = 318
2x + 2x + 210 = 318
4x = 108
x = 27
The length is 27 meters long, and the width is 132 meters wide.
