Find x in the following : 3 × - 6 + x = 3 × - 6 + 3 × 10

Distributive property is expressed as, a × ( b + c ) = ( a × b ) + ( a × c ) . 3 × - 6 + x = 3 × - 6 + 3 × 10 L.H.S. 3 × - 6 + x = 3 × - 6 + 3 × 10 3 × x - 6 = - 18 + 30 3 x - 18 = - 18 + 30 3 x = 30 x = 10 "Hence, the required solution is obtained".

Find x in the following : - 18 × - 7 + 3 = - 18 × x + - 18 × 3

Distributive property is expressed as, a × ( b + c ) = ( a × b ) + ( a × c ) . - 18 × - 7 + 3 = - 18 × x + - 18 × 3 - 18 × - 7 + 3 = - 18 X + - 54 - 18 - 4 = - 18 X - 54 72 = - 18 x - 54 72 + 54 = - 18 x 126 = - 18 x X - 7 "Hence, the required solution is obtained".

Find x in the following : x × 6 + - 8 = 15 × 6 + - 8 × 15

Distributive property is expressed as, a × ( b + c ) = ( a × b ) + ( a × c ) . x × 6 + - 8 = 15 × 6 + - 8 × 15 x × 6 - 8 = 15 × 6 + - 8 × 15 x × - 2 = 90 + - 120 - 2 x = 90 - 120 - 2 x = - 30 x = 15 "Hence, the required solution is obtained".

Find x in the following : 6 × - 5 + x = 6 × - 5 + 6 × 7

Distributive property is expressed as, a × ( b + c ) = ( a × b ) + ( a × c ) . 6 × - 5 + x = 6 × - 5 + 6 × 7 6 x - 5 = - 30 + 42 6 x - 5 = - 30 + 42 6 x - 6 × 5 = 12 6 x - 30 = 12 6 x = 12 + 30 = 42 X = 42 6 X = 7 "Hence, the required solution is obtained".

Find x in the following : - 19 × 4 + - 2 = - 19 × 4 + - 19 × x

Distributive property is expressed as, a × ( b + c ) = ( a × b ) + ( a × c ) . - 19 × 4 + - 2 = - 19 × 4 + - 19 × x - 19 × 4 - 2 = - 19 × 4 - 19 × x - 19 2 = - 76 - 19 x - 38 + 76 = - 19 x 38 = - 19 x - 19 x = 38 x = - 2 "Hence, the required solution is obtained".

Find x in the following : 8 × - 7 + - 5 = x × - 7 + x × - 5

Distributive property is expressed as, a × ( b + c ) = ( a × b ) + ( a × c ) . 8 × - 7 + - 5 = x × - 7 + x × - 5 8 × - 7 - 5 = x × - 7 + x × - 5 8 - 12 = - 7 x + - 5 x - 96 = - 7 x - 5 x - 96 = - 12 x - 12 x = - 96 x = 96 12 = 8 "Hence, the required solution is obtained".
