Question

Solve 92 = - 4(2r - 5)

hintHint:

An equation in which highest power of any variable is always 1 is known as a Linear equation.
We will simplify the given equation and find the value of r.

The correct answer is: Value of r for the given equation is - 9


    Step-by-step solution:-
    92 = -4 (2r - 5)
    fraction numerator 92 over denominator negative 4 end fraction = 2r - 5 ….................................................. (Dividing both sides by -4)
    ∴ - 23 = 2r - 5
    ∴ - 23 + 5 = 2r …....................................................... (Taking all constants together)
    ∴ - 18 = 2r
    fraction numerator negative 18 over denominator 2 end fraction = r ........................................................... (Dividing both sides by 2)
    ∴ - 9 = r
    Final Answer:-
    ∴ Value of r for the given equation is -9.
