The sum of the 2 pieces will be 98 in. so it will look like

And since the 2nd piece is 10 in longer

A-B=10
A+B=98
SINCE THEY GAVE YOU HOW TO CONVERT A TO B, DO IT, SO YOU HAVE 1 VARIABLE IN ONE EQUATION, WITCH IS SOLVABLE
A+B=98
B+10+B=98
2B=98-10
2B=88
B=44
NOW USE B TO GET A BY SUBSUTUTING B WITH 44.
A-B=10
A-44=10
A=10+44
A=54
CHECK BY SUBSUTUTING A WITH 54 AND B WITH 44
54+44=98
98=98
A=54INCHES
B=44INCHES
