Question

0,75(2x+5)+0.25(x+3)=0,75 Пожалуйста, помогите срочно!!

Answer 1

1,5x+3,75+0,25x+0,75=0,75
1,75x+3,75=0
1,75x=-3,75
175x=375
x=375/175
x=25/7
x=2 1/7

Answer 2

Solving the Equation

To solve the equation 0.75(2x+5) + 0.25(x+3) = 0.75, we can follow these steps:

1. Distribute the constants: - 0.75 * 2x + 0.75 * 5 + 0.25 * x + 0.25 * 3 = 0.75 - 1.5x + 3.75 + 0.25x + 0.75 = 0.75 - 1.75x + 4.5 = 0.75

2. Combine like terms: - 1.75x + 4.5 = 0.75 - 1.75x = 0.75 - 4.5 - 1.75x = -3.75

3. Solve for x: - x = -3.75 / 1.75

Let's calculate the value of x.

Calculation

Using the equation x = -3.75 / 1.75, we find: - x ≈ -2.14

So, the solution to the equation 0.75(2x+5) + 0.25(x+3) = 0.75 is x ≈ -2.14.

This calculation is based on the given equation and the steps for solving it.
