Answer 2

To solve the equation 3x - 2.1 = 6.3, we substitute the value of x as -1.4 and check if it satisfies the equation.

Let's plug in x = -1.4 into the equation:

3(-1.4) - 2.1 = 6.3 -4.2 - 2.1 = 6.3 -6.3 = 6.3

The left-hand side of the equation is not equal to the right-hand side. Therefore, x = -1.4 is not a solution to the equation 3x - 2.1 = 6.3.
