Question

7x-3=x+9, 4x-5,6=3x-2,7​

Answer 1

Ответ:

Пошаговое объяснение:

7х-3=х+9

7х-х=9+3

6х=12

х=2

4х-5.6=3х-2.7

4х-5.6+2.7=3х

4х-5.6+2.7=4х-х

5.6-2.7=х

х=2.9

Answer 2

Let's solve each equation step by step:

1. 7x - 3 = x + 9:

To solve this equation, we want to isolate the variable x on one side of the equation. We can do this by performing various operations to both sides of the equation. Let's start by subtracting x from both sides to eliminate x from the right side:

7x - x - 3 = x - x + 9

Simplifying:

6x - 3 = 9

Next, we can add 3 to both sides to isolate the term with x:

6x - 3 + 3 = 9 + 3

Simplifying:

6x = 12

To solve for x, divide both sides of the equation by 6:

(6x)/6 = 12/6

Simplifying:

x = 2

So the solution to the equation is x = 2.

2. 4x - 5,6 = 3x - 2,7:
