Question

5(2х-7)-4(1+3х) = 7х+35

Answer 1

Ответ:

x=-74/9          /-дробь

Пошаговое объяснение:

5(2x-7)-4(1+3x)=7x+35

10x-25-4-12x=7x+35

-2x-39=7x+35

-2x-7x=35+39

-9x=74

x= -74/9      /-дробь

Answer 2

Ответ:

$10x - 35 - 4 - 12x = 7x + 35 \\ 10x - 12x - 7x = 35 + 35 + 4 \\ - 9x = 74 \\ x = 74 \div ( - 9) \\ x = \frac{74}{ - 9} \\ x = - 8 \frac{2}{9}$

Answer 3

Let's solve the equation step by step:

5(2x - 7) - 4(1 + 3x) = 7x + 35

First, we'll distribute the multiplication:

10x - 35 - 4 - 12x = 7x + 35

Combine like terms on both sides:

(10x - 12x) - 35 - 4 = 7x + 35

-2x - 39 = 7x + 35

Next, we'll isolate the variable terms on one side and the constant terms on the other side:

-2x - 7x = 35 + 39

-9x = 74

To solve for x, we'll divide both sides of the equation by -9:

x = 74 / -9

x ≈ -8.22

Therefore, the solution to the equation is x ≈ -8.22.
