Question

Six more than the product of seven and a number is 55.

Which equation and solution correctly represent this sentence?

Answer 1

Answer:

Let the required number be x.

Atq,

$\: \: \: \: \: \: (7 \times x )+ 6 = 55$

$= > 7x + 6 = 55$

$= > 7x = 55 - 6$

$= > 7x = 49$

$= > x = \frac{49}{7 }$

$= > x = 7$

Hence the required number = 7

Verification :

$= > 7x + 6 = 55$

$= >(7 \times 7) + 6 = 55$

$= > 49 + 6 = 55$

$= > 55 = 55$
