Question

2.4х - 1.5 - 5.7Решить уравнение. Я решила, но не уверена, что правильно.у меня х=1.75

Answer 1

2,4x-1,5-5,7=0;

2,4x=7,2;

x=3

Answer 2

To solve the equation 2.4x - 1.5 - 5.7 = 0, we need to simplify and isolate the variable x.

First, we can simplify the left side of the equation by combining like terms:

2.4x - 1.5 - 5.7 = 0

2.4x - 7.2 = 0

Next, we can add 7.2 to both sides of the equation to isolate the variable x:

2.4x - 7.2 + 7.2 = 0 + 7.2

2.4x = 7.2

Finally, we can divide both sides of the equation by 2.4 to solve for x:

2.4x/2.4 = 7.2/2.4

x = 3

Therefore, the solution to the equation 2.4x - 1.5 - 5.7 = 0 is x = 3, not x = 1.75.
