Question

1) 3(х – 2) = х + 2 2) 3,4 + 2х = 7(х – 2,3)

Answer 1

Ответ:

3х-6=х+2

2х=8

Х=4

3,4+2х=7х-16,1

19,5=5х

3,9=х

Answer 2

Ответ:

1)

Пошаговое объяснение:

1) 3х-6= х+2

3х-х= 2-6

2х= -4

х=-4/2

х= -2

2) 3,4 +2х= 7х-16,1

2х-7х= -16,1 -3,4

-5х= -19,5

х= 3,9

Answer 3

Sure, let's solve the equations step by step.

Equation 1: $3(x - 2) = x + 2$

First, distribute the 3 on the left side of the equation:

$3x - 6 = x + 2$

Next, move all the x terms to one side and the constant terms to the other side:

$3x - x = 2 + 6$ $2x = 8$

Now, divide by 2 to solve for x:

$x = 4$

So, the solution for the first equation is $x = 4$.

Equation 2: $3.4 + 2x = 7(x - 2.3)$

First, distribute the 7 on the right side of the equation:

$3.4 + 2x = 7x - 16.1$

Next, move all the x terms to one side and the constant terms to the other side:

$2x - 7x = -16.1 - 3.4$ $-5x = -19.5$

Now, divide by -5 to solve for x:

$x = 3.9$

So, the solution for the second equation is $x = 3.9$.
