[tex]\\ \rm\longmapsto \dfrac{5b}{12}=5[/tex]
[tex]\\ \rm\longmapsto 5b=12(5)[/tex]
[tex]\\ \rm\longmapsto 5b=60[/tex]
[tex]\\ \rm\longmapsto b=\dfrac{60}{5}[/tex]
[tex]\\ \rm\longmapsto b=12[/tex]
Step-by-step explanation:
[tex] \frac{5b}{12} = 5 \\ by \: cross \: multiplicatin \\ 5b = 5 \times 12 \\ 5b = 60 \\ b = \frac{6 0 }{5} \\ b = 12[/tex]
