Question

6 х - 7(3 х- 5)- 2(4х-7) = 3 Помогите решить.

Answer 1

Ответ:

x=2

Пошаговое объяснение:

6x-7(3x-5)-2(4x-7)=3

6x-21x+35-8x+14=3

-23x+49=3

-23x=-46

x=2

Answer 2

6х - 7(3х-5) - 2(4х-7) - 3 = 0

6х - 21х- 35 - 8х - 14 - 3 = 0

все цифры одной "масти" сокращаются

-23х - 52 = 0

-23х = 52

23х=52

х= 2,3

Answer 3

Let's simplify the left-hand side of the equation step by step:

6x - 7(3x - 5) - 2(4x - 7) = 3

First, let's simplify the expression inside the parentheses by distributing the -7 and -2:

6x - 7(3x) + 7(5) - 2(4x) + 2(7) = 3

Simplifying further by multiplying:

6x - 21x + 35 - 8x + 14 = 3

Now we can combine like terms:

-23x + 49 = 3

Subtracting 49 from both sides:

-23x = -46

Dividing by -23:

x = 2

Therefore, the solution to the equation is x = 2.
