Question

(7-8х)-(9-12х)+(5х+4)=-16

Answer 1

Ответ:

$x=1\frac{5}{9}$

Пошаговое объяснение:

(7-8x)-(9-12x)+(5x+4)=-16

7-8x-9+12x+5x+4-16=0

9x-14=0

9x=14

$x=\frac{14}{9}\\ x=1\frac{5}{9}$

Answer 2

Ответ:

Answer 3

To solve the given equation:

(7 - 8x) - (9 - 12x) + (5x + 4) = -16

First, let's simplify each side of the equation:

7 - 8x - 9 + 12x + 5x + 4 = -16

Combine like terms:

-8x + 12x + 5x + 7 - 9 + 4 = -16

(-8x + 12x + 5x) is equivalent to 9x:

9x + 7 - 9 + 4 = -16

Combine the constants:

(7 - 9 + 4) is equivalent to 2:

9x + 2 = -16

Now, let's isolate the variable term by subtracting 2 from both sides:

9x + 2 - 2 = -16 - 2

9x = -18

Finally, divide both sides by 9 to solve for x:

(9x)/9 = (-18)/9

x = -2

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