Question

7(3-x)-(3x-4)= 5(3+2x)-2(-3-2x)

Answer 1

7 - 2 * (3 - х) = 4 * (х - 1) + 5
7 - 6 + 2х = 4х - 4 + 5
2х - 4х = - 4 + 5 - 7 + 6
- 2х = 0
х = 0 : (- 2)
х = 0
--------------------------------------
Проверка: 7 - 2 * (3 - 0) = 4 * (0 - 1) + 5
                7 - 6 = - 4 + 5
                1 = 1

Answer 2

21-7x-3x+4=15+10x+6+4x
x переносим все вправо, числа влево и считаем..
-24x=-4
x=1/6

Answer 3

Let's begin by simplifying both sides of the equation:

7(3-x)-(3x-4)= 5(3+2x)-2(-3-2x)

21 - 7x - 3x + 4 = 15 + 10x + 6 + 4x

Combine like terms on each side:

18 - 10x = 21x + 21

Subtract 21 from both sides:

-3 - 10x = 21x

Add 10x to both sides:

-3 = 31x

Divide both sides by 31:

x = -3/31

Therefore, the solution to the equation is x = -3/31.
