Question

3.5x-2.8=1.4x+1.4 2) 3.6x-2.5=1.2x+2.3

Answer 1

Ответ:

Пошаговое объяснение:

3.5x-2.8=1.4x+1.4

3,5x - 1,4x = 1,4 + 2,8

2,1x = 4,2

x = 4,2 : 2,1

x = 2

2)

3.6x-2.5=1.2x+2.3

3,6x - 1,2x = 2,3 + 2,5

2,4x = 4,8

x = 4,8 : 2,4

x = 2

Answer 2

1) 3.5х-1,4х=1.4+2.8

2.1х= 4.2

х= 2

2) 3.6х-1.2х=2.3+2.5

2.4х= 4.8

х= 2

Answer 3

To solve the equations, we need to isolate the variable "x" on one side of the equation. Here's how we can solve each equation step by step:

1. 3.5x - 2.8 = 1.4x + 1.4

Step 1: Move the constant terms to one side of the equation and the variable terms to the other side: 3.5x - 1.4x = 1.4 + 2.8

Step 2: Combine like terms: 2.1x = 4.2

Step 3: Divide both sides by the coefficient of x to solve for x: x = 4.2 / 2.1 x = 2

So the solution to the first equation is x = 2.

2. 3.6x - 2.5 = 1.2x + 2.3

Step 1: Move the constant terms to one side of the equation and the variable terms to the other side: 3.6x - 1.2x = 2.3 + 2.5

Step 2: Combine like terms: 2.4x = 4.8

Step 3: Divide both sides by the coefficient of x to solve for x: x = 4.8 / 2.4 x = 2

So the solution to the second equation is x = 2.
