Question

4х - 1,6= 6х - 7,6 4,7х-1,8=3,2+2,2х

Answer 1

1)4x-1.6=6x-7.6

4x-6x=-7.6+1.6

-2x=-6

2x=6

x=3

2) 4.7x-1.8=3.2+2.2x

4.7x-2.2x=3.2+1.8

2.5x=5

x=2

Answer 2

4х - 1,6= 6х - 7,6

4x-6x=-7,6+1,6

-2x=-6

x=3

Answer 3

To solve the given equations, we need to find the values of 'x' that satisfy the equations. Let's solve them one by one:

1. 4x - 1.6 = 6x - 7.6

First, we need to isolate the 'x' term on one side of the equation. Let's do that:

Subtract 4x from both sides: 4x - 4x - 1.6 = 6x - 4x - 7.6

Simplify: -1.6 = 2x - 7.6

Next, isolate the 'x' term by adding 7.6 to both sides: -1.6 + 7.6 = 2x - 7.6 + 7.6

Simplify: 6 = 2x

Now, divide both sides by 2 to solve for 'x': x = 6/2 x = 3

So, the solution for the first equation is x = 3.

2. 4.7x - 1.8 = 3.2 + 2.2x

First, let's simplify the equation by combining like terms:

Subtract 2.2x from both sides: 4.7x - 2.2x - 1.8 = 3.2

Simplify: 2.5x - 1.8 = 3.2

Next, isolate the 'x' term by adding 1.8 to both sides: 2.5x - 1.8 + 1.8 = 3.2 + 1.8

Simplify: 2.5x = 5

Finally, divide both sides by 2.5 to solve for 'x': x = 5/2.5 x = 2

So, the solution for the second equation is x = 2.

In summary:

1. For the equation 4x - 1.6 = 6x - 7.6, the solution is x = 3.
2. For the equation 4.7x - 1.8 = 3.2 + 2.2x, the solution is x = 2.
