Question

fraction numerator q plus 1 over denominator 2 end fraction equals fraction numerator q minus 1 over denominator 3 end fraction

hintHint:

An equation with variables on both sides of the "equal to" sign i.e. on LHS and RHS can be solved by first simplifying both the sides (Opening up the brackets, addition, subtraction, i.e. if any) and then all the variables are taken on 1 side of the equation and all the constants i.e. numbers on the other side. Both sides are then simplified further and the solution is obtained

The correct answer is: Value of q for the given equation is -5.


    Step-by-step solution:-
    fraction numerator q plus 1 over denominator 2 end fraction equals fraction numerator q minus 1 over denominator 3 end fraction
                                                                                        ∴ 3 × (q + 1) = 2 × (q - 1) ................................. (Cross-multiplying)
                                                                              ∴ (3 × q) + (3 × 1) = (2 × q) - (2 × 1) ..................... [Distributive property- a (m+n) = am + an]
                                                                                             ∴ 3q + 3 = 2q - 2
                                                                                             ∴ 3q - 2q = -2 - 3 …....................... (Taking all variables and constants on either sides of                                                                                                                                                                                                                       the equation)
                                                                                                    ∴ q = -5
    Final Answer:-
    ∴ Value of q for the given equation is -5.
