5.1

5.5

6.0

6.5
explain please

Answer 1

i assume this is
\[\frac{b+2}{3}-\frac{b-2}{7}=2\]

Answer 2

your best bet is to multiply both sides by the least common multiple of \(3\) and \(7\), namely \(21\)

Answer 3

\[21\left(\frac{b+2}{3}-\frac{b-2}{7}\right)=2\times 21\]or
\[7(b+2)-3(b-2)=42\] then solve that one

Answer 4
