for them to pay the same amount.

Answers

  1. The equations are t+6c=150, t+3c=75.
    An equation is a formula that expresses the equivalency of two expressions, by connecting them with the equals sign = . The word equation and its cognates in other languages may have subtly different meanings; for illustration, in French an équation is defined as containing one or further variables, while in English, any well- formed formula conforming of two expressions related with an equals sign is an equation.
    Working an equation containing variables consists of determining which values of the variables make the equivalency true. The variables for which the equation has to be answered are also called unknowns, and the values of the unknowns that satisfy the equivalency are called results of the equation. There are two kinds of equations individualities and tentative equations. An identity is true for all values of the variables. A tentative equation is only true for particular values of the variables.
    Here,
    t is table and,c is chair
    So,
    The equation for find the cost for them to pay the same amount is t + 6c = 150, t + 3c = 75.
    After solving, t = 0, c = 25.
