Answer 1

Ответ:

Пошаговое объяснение:

7,5x=0

Х=0:7,5

Х=0

15-3x=5,1

3х=15-5,1

3х=9,9

Х=9,9:3

Х=3,3

3x+2x=15,5

5х=15,5

Х=15,5:3

Х=5,1

Answer 2

To solve these equations, I will solve each of them step by step.

1. 7.5x = 0: To find the value of x, we can divide both sides by 7.5: $x = 0/7.5 = 0$

2. 15 - 3x = 5: First, let's isolate the term with x on one side: $15 - 5 = 3x$ $10 = 3x$

Now, divide both sides by 3 to solve for x: $x = 10/3 = 3.33$

3. 13x + 2x = 15.5: Combine the x terms on the left-hand side: $15x = 15.5$

Then, divide both sides by 15: $x = 15.5/15 = 1.0333$

So the solutions for the equations are: $x = 0$ $x = 3.33$ $x = 1.0333$
