Solve the equation. then check your solution. –4.2 = –2.1n a. 2 c. 2.1 b. –2 d. –6.3 please select the best answer from the choices provided a b c d

Answer 1

To solve the equation -4.2 = -2.1n, divide both sides by -2.1 to isolate the variable n. The solution is n = 2. Check the solution by substituting it back into the original equation.

Step-by-step explanation:

To solve the equation -4.2 = -2.1n, we need to isolate the variable n. We can do this by dividing both sides of the equation by -2.1. This gives us n = -4.2 / -2.1 = 2.

To check our solution, we substitute n = 2 back into the original equation: -4.2 = -2.1(2). Simplifying this equation gives us -4.2 = -4.2, which is true. Therefore, our solution n = 2 is correct.
