Question

Найдите значение х, при котором значение у =0,6 у=-0,02 у=2х-1

Answer 1

1.у=2х-1
-0,02=2х-1
-0,02+1=2х
2х=0,98
х=0,98/2
х=0,49

2.0,6=2х-1
0,6+1=2х
2х=1,6
х=1,6/2
х=0,8

Answer 2

To find the value of x when y takes three different values, we can set up a system of equations and then solve for x.

Given:

1. y = 0.6
2. y = -0.02
3. y = 2x - 1

Since all three expressions are equal to y, we can equate them to each other:

0.6 = -0.02 = 2x - 1

Now, we can solve for x:

1. 0.6 = 2x - 1 Add 1 to both sides:
2. 0.6 + 1 = 2x
3. 1.6 = 2x Divide both sides by 2:
4. x = 1.6 / 2
5. x = 0.8

So, the value of x when y takes the given values is x = 0.8.
