The south memorial school is designing a new playground. There will be a walk with it diagonally across is the square playground. The walkway is 55 m long. Final length of one side, round your answer to the nearest 10th

-26n -22= n - 90

-26 times a number: -26n

minus 22: -22

equal: =

90 less than a number: n - 90

Solving the Equation:

Move n to the left side of the equal sign (which becomes -n) in order to combine like terms:

-26n-n-22= -90

Move -22 to the right side of the equal sign which becomes +22

-26n-n=-90+22

solve both sides; -26n-n= -27n and -90+ 22= -78

-27n=-78

n= 2.888888
