Question

3(х-0,8)+2,6=-7х-4(0,7-2х)+6 ​

Answer 1

$3x - 2.4 + 2.6 = - 7x - 2.8 + 8x + 6 \\ 3x + 0.2 = x + 3.2 \\ 3x - x = 3.2 - 0.2 \\ 2x = 3 \\ x = \frac{3}{2} \\ x = 1 \frac{1}{2}$

Answer 2

3(х-0,8)+2,6=-7х-4(0,7-2х)+6
3х-2,4+2,6=-7х-2,8+8х+6
3х+0,2=х+3,2
3х-х=3,2-0,2
2х=3
х=1,5

Answer 3

To solve the equation, let's simplify and solve for x step by step:

3(x - 0.8) + 2.6 = -7x - 4(0.7 - 2x) + 6

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

3x - 2.4 + 2.6 = -7x - 2.8 + 8x + 6

Combine like terms:

3x + 0.2 = x + 3.2

Now, let's isolate the variable x on one side of the equation. To do this, we'll subtract x from both sides:

3x - x + 0.2 = x - x + 3.2

Simplifying further:

2x + 0.2 = 3.2

Next, we'll subtract 0.2 from both sides:

2x + 0.2 - 0.2 = 3.2 - 0.2

Simplifying again:

2x = 3

Finally, divide both sides of the equation by 2 to solve for x:

(2x)/2 = 3/2

x = 3/2

So, the solution to the equation is x = 3/2 or 1.5.
