How to solve for x

x - 6.41 = 1.8

I want to know the reason why it equals to 1.8 I forgot how to do this and I need help

Answer 1

8.21

Explanation:

To solve for x in the equation:

x - 6.41 = 1.8 (or 1.80)

We want to isolate x on one side of the equation.

First, we can add 6.41 to both sides of the equation:

x - 6.41 + 6.41 = 1.8 + 6.41

Simplifying the left-hand side by canceling out the -6.41 and +6.41, we get:

x = 1.8 (cough cough --> 1.80) + 6.41

x = 8.21

Therefore, the solution is x = 8.21.

Note that adding 6.41 to both sides of the equation is equivalent to moving -6.41 to the right-hand side of the equation, which changes its sign to +6.41. Also, in this case, since 1.8 and 1.80 are the same number, we can treat them interchangeably in the calculations.
