Question

4х-1целая 4 пятых=5,4

Answer 1

Ответ:

4x - 1$\frac{4}{5}$ = 5,4;

5 * 4x - $\frac{9}5}$ * 5 = 5,4 * 5;

20x - 9 = 27;

20x = 27 + 9;

20x = 36;

x = 36/20;

x = 1,8;

Answer 2

To solve the equation, we need to isolate the variable "x." Let's break down the given equation step by step:

4x - 1 + 4/5 = 5.4

Step 1: Add 1 to both sides to eliminate the constant term on the left side of the equation.

4x - 1 + 1 + 4/5 = 5.4 + 1

This simplifies to:

4x + 4/5 = 6.4

Step 2: Subtract 4/5 from both sides to move it to the right side of the equation.

4x + 4/5 - 4/5 = 6.4 - 4/5

This simplifies to:

4x = 5.8

Step 3: Finally, divide both sides by 4 to solve for "x."

4x / 4 = 5.8 / 4

x = 1.45

So the solution to the equation is x = 1.45.
