For this item, let us represent the unknown number by the variable x. The left hand side of the equation is expressed as,
                                     2x + 5
where the number is multiplied by 2 and then 5 is added to the product. For the right hand side,
                                     4x - 7
Equating the two, the equation becomes,
                             2x + 5 = 4x - 7
