Question

_____________ subtracted from 6700 is same as 150 added to 6550​

Answer 1

$\bold\green{let \: the \: number \: be \: x} \\ \bold\green{x - 6700} = \bold\green{150 + 6500} \\ \bold{x = 150 + 6500 + 6700} \\ \bold{x = 13350}$

according to this

13350 - 6700 = 150 + 6500

$\bold\red{13350 - 6700 = 150 + 6500} \\ \bold{6650 = 6650} \\ \bold\green{ \: hence \: Lhs = Rhs \: proved ✓ \: \: } \\ \bold\green{condition \: satisfied \: ✓} \:$
