I don’t understand anything online school is hard.

To find this, set the opposite ends equal to one another and solve for n

5n-6 = 3n-2  subtract 3n from both sides
2n-6 = -2      add 6 to both sides
2n = 4          divide both sides by 2
n=4

now use this to solve for the sides
5n-6
5(2) -6
4
and 
2n+3
2(2) +3
7
adjacent means next to each other so it is 4 and 7 +B

Brainliest is always appreciated !
