Answer 1

$21 \times ( - x) \times ( - 5) = 45 \times ( - 6) \\ 105x = - 270 \\ x = - 2 \frac{4}{7}$

Answer 2

Solving the Equation

To solve the equation 21×(-X)×(-5) = 45×(-6), we can follow these steps:

1. Simplify the Equation: - First, simplify both sides of the equation.

2. Isolate the Variable: - Then, isolate the variable to find its value.

Simplifying the Equation

Let's start by simplifying both sides of the equation.

21×(-X)×(-5) = 45×(-6)

21×X×5 = 45×(-6) (Multiplying two negative numbers gives a positive result)

105X = -270 (Simplified the equation)

Isolating the Variable

Now, let's isolate the variable X to find its value.

X = -270 / 105 X = -2.5714285714285716

So, the solution to the equation 21×(-X)×(-5) = 45×(-6) is: X = -2.5714285714285716
