Question

0.8*(3х-0.2)=4*(0.5х-0.7)

Answer 1

0,8(3х-0,2)=4(0,5х-0,7)
2,4х-0,16=2х-2,8
0,4х=-2,64
х=-6,6
Ответ: х=-6,6

Answer 2

To solve the equation, we'll start by simplifying both sides of the equation and then isolating the variable 'x'.

Let's simplify the equation step-by-step:

1. Distribute the multiplication on both sides: 0.8 * 3x - 0.8 * 0.2 = 4 * 0.5x - 4 * 0.7

2. Simplify the terms: 2.4x - 0.16 = 2x - 2.8

3. Move the terms containing 'x' to one side and the constant terms to the other side to isolate 'x': 2.4x - 2x = 2.8 - 0.16

4. Combine the 'x' terms and the constant terms: 0.4x = 2.64

5. Solve for 'x' by dividing both sides by 0.4: x = 2.64 / 0.4 x = 6.6

So, the value of 'x' that satisfies the equation is 6.6.
