Answer 1

Answer

these is your answer.

I hope it's helpful

Answer 2

On simplifying the bracket, we get

=> ( 6 × 1 ) - ( 6 × 4x ) + ( 7 × 2 ) + ( 7 × 5x ) = 53

=> 6 - 24x + 14 + 25x = 53

=> 20 + 11x = 53

Subtracing 20 from both sides, we get 20 + 11x - 20 = 53 - 20

11x = 53

Dividing both sides by 11, we get

=> 11x / 11 = 33 / 11

=> x = 3

Verification:

=> Substituting x = 3 in LHS, we get

=> 6 ( 1 - 4 × 3 ) + 7 ( 2 + 5 × 3 ) = 53

=> 6 ( 1 - 12 ) + 7 ( 2 + 15 ) = 53

=> 6 ( - 11 ) + 7 ( 17 ) = 53

=> - 66 + 119 = 53

=> 53 = 53

Therefore LHS = RHS

Hence, verified.

I hope this will help you dear..
