Question

Б) 6-8(x + 2)= 2-2xВ) 3(4-2x)+6=-2x+4​

Answer 1

Б) 6-8(х+2)=2-2х

6-8х-16=2-2х

-10-8х=2-2х

-8х+2х=2+10

-6х=12

х= -2

В) 3(4-2х)+6= -2х+4

12-6х+6=-2х+4

18-6х=-2х+4

-6х+2х=4-18

-4х= -14

х=7/2(дробью) или х=3 целых 1/7 (дробью) х=3,5

P/s надеюсь всё понятно

Answer 2

Ответ:

Б)

6-8х-16=2-2х (когда перед скобками минус все знаки внутри скобки меняются на противоположные)

-8х+2х=2+16-6 (х в одну сторону а все цифры в другую)

-6х=12

х=-2

В)

12-6х+6=-2х+4

18-6х=-2х+4

-6х+2х=4-18

-4х=-14

х=3,5 (7/2)

Answer 3

To solve these equations, let's start by simplifying the expressions and isolating the variable terms. Here's how you would solve each equation step by step:

Equation A: 6 - 8(x + 2) = 2 - 2x

First, distribute the -8 on the left side: 6 - 8x - 16 = 2 - 2x

Combine like terms on both sides: -8x - 10 = -2 - 2x

Subtract -2x from both sides: -6x - 10 = -2

Add 10 to both sides: -6x = 8

Divide by -6: x = -8/6 x = -4/3

Equation B: 3(4 - 2x) + 6 = -2x + 4

Distribute the 3 on the left side: 12 - 6x + 6 = -2x + 4

Combine like terms on both sides: 18 - 6x = -2x + 4

Subtract -2x from both sides: -6x + 2x = 4 - 18

Simplify: -4x = -14

Divide by -4: x = 14/4 x = 7/2

So, the solutions for the given equations are: A) x = -4/3 B) x = 7/2
