Answer 2

1. To solve the equation (х - 2/5) = 3/4, we can begin by isolating the variable х.

Let's solve it step by step:

х - 2/5 = 3/4

First, let's get rid of the fraction by multiplying both sides of the equation by the least common denominator (LCD), which in this case is 20:

20 * (х - 2/5) = 20 * (3/4)

Simplifying:

20х - 8 = 15

Next, let's isolate the variable х by moving the constant term to the other side of the equation:

20х = 15 + 8

20х = 23

Finally, divide both sides of the equation by 20 to solve for х:

х = 23/20

Therefore, the solution to the equation (х - 2/5) = 3/4 is х = 23/20.

2. To solve the equation х + 6 = 0, we can isolate the variable х.

Let's solve it step by step:

х + 6 = 0

To isolate х, we subtract 6 from both sides of the equation:

х = -6

Therefore, the solution to the equation х + 6 = 0 is х = -6.
