x $=\frac{1n}{n}$ Which becomes: x=1 where $1

Work Step by Step

Since there are 4 columns in each row, we will use n to be between 1 and 4, where n = column number. Plugging in 1 through 4 for each n, We get: x=$\frac{1\times1}{1}=1$ x=$\frac{1\times2}{2}=1$ x=$\frac{1\times3}{3}=1$ x=$\frac{1\times4}{4}$=1$ Thus, all columns yield 1.
