One column of numbers consists of 28, 42, and 14. when the digits of the
numbers are added together, the result is 2+8+ 4+2*1* 4.21, and when
the digits of 21 are then added together, the end result is 2*1*3. if the
same process is performed on the numbers in a second column, what can be
concluded?

Clara solved the equation 7/3x = −2/3 as shown → 7/3x( 3/7 ) = −2/3 ( 3/7 ) x = −14 what is clara’s error?
