●》This is an equation, equation means both side term equal that L.H.S = R.H.S.

Solution:-

☆ According to note first point~

▪︎$3n = 21$

▪︎$n = 21 ÷ 3$

☆ After doing calculations~

▪︎$n = 7$

Checking

☆ According to note second point~

▪︎$3n = 21 ?$

▪︎$3 × 7 = 21 ?$

▪︎$21 = 21 ?$ ( yes )

Hence, proved that L.H.S = R.H.S or both side term is equal //
