x = 58/3 = 19 1/3 = 19.333333

I'm attaching a screenshot showing this rule.

I'm using the letters from the rule shown on the screenshot bc this is the common formula used.

AB x AD = AC x AE

In your problem:

AB = 16+26=42
AD = 16

AC = 18+x

AE = 18

Substitute:

AB x AD = AC x AE

42 x 16 = (18+x)(18)

672 = 18x+18*18

672 = 18x + 324

672-324 = 18x

348 = 18x

x = 348/18 = 58/3 = 19 1/3 = 19.333333

Check:

AB x AD = AC x AE

42x16 = (18+(58/3))(18)

672 = 672
