Question

Определить при каком значении x значение функции y=2x-1 равно 5

Answer 1

Х=3

Это ответ 2×3=6 6 -1=5

Answer 2

To find the value of x when the function y = 2x - 1 is equal to 5, you need to solve the equation for x.

The equation is: y = 2x - 1

And we know that y = 5.

So, we can write the equation as: 5 = 2x - 1

To find the value of x, follow these steps:

Step 1: Add 1 to both sides of the equation to isolate the term with 2x: 5 + 1 = 2x - 1 + 1

Step 2: Simplify: 6 = 2x

Step 3: Divide both sides by 2 to solve for x: x = 6 / 2

Step 4: Simplify the right side: x = 3

So, when x is equal to 3, the value of the function y = 2x - 1 is 5.
