Question

1)6(2х-4)-4х+5=14 2)-17(х+2)=2(х-3) 3)2х-4+6х-3=2(х-1) 4)-4(х-2)+6х=2х

Answer 1

Ответ:

1) 12x-24-4x+5=14

12x-4x=24-5+14

8x=33

x=4,125

2)-17x-34=2x-6

-17x-2x=34-6

-19x=28

x=

$- \frac{28}{19}$

3) 2x-4+6x=2x-2

2x+6x-2x=4-2

6x=2

x=

$\frac{1}{3}$

4) -4x+8+6x=2x

-4x+6x-2x=8

0=8, значит, корней нет.

Answer 3

It looks like you've provided a set of equations. Let's solve them one by one:

1. $6(2x-4) - 4x + 5 = 14$ Let's simplify and solve for $x$:

Distribute: $12x - 24 - 4x + 5 = 14$ Combine like terms: $8x - 19 = 14$ Add 19 to both sides: $8x = 33$ Divide by 8: $x = \frac{33}{8}$

So, the solution for the first equation is $x = \frac{33}{8}$.

2. $-17(x+2) = 2(x-3)$ Let's simplify and solve for $x$:

Distribute: $-17x - 34 = 2x - 6$ Combine like terms: $-17x - 2x = -6 + 34$ Simplify: $-19x = 28$ Divide by -19: $x = -\frac{28}{19}$

The solution for the second equation is $x = -\frac{28}{19}$.

3. $2x - 4 + 6x - 3 = 2(x - 1)$ Let's simplify and solve for $x$:

Combine like terms: $8x - 7 = 2x - 2$ Subtract 2x from both sides: $6x - 7 = -2$ Add 7 to both sides: $6x = 5$ Divide by 6: $x = \frac{5}{6}$

So, the solution for the third equation is $x = \frac{5}{6}$.

4. $-4(x - 2) + 6x = 2x$ Let's simplify and solve for $x$:

Distribute: $-4x + 8 + 6x = 2x$ Combine like terms: $2x + 8 = 2x$ Subtract $2x$ from both sides: $8 = 0$

In this case, the equation has no solution. The equation is inconsistent and doesn't lead to a valid value for $x$.

To recap:

1. $x = \frac{33}{8}$
2. $x = -\frac{28}{19}$
3. $x = \frac{5}{6}$
4. No solution (inconsistent equation)
