Question

9(3х - 2) - 6 = 5(4х - 1 ) + 2

Answer 1

Ответ:

Пошаговое объяснение:

27х - 18 - 6 = 20х - 5 + 2

27х - 24 = 20х -3

27х - 20х = -3 + 24

7х = 21

х = 3

Answer 2

Ответ:

x = 3

Пошаговое объяснение:

9( 3x - 2) - 6 = 5( 4x - 1) + 2

27x - 18 - 6 = 20x - 5 +2

27x - 20x = - 5 +2 +18 + 6

7x = 21

x = 3

Answer 3

Let's solve the given equation step by step:

9(3x - 2) - 6 = 5(4x - 1) + 2

First, let's simplify the expressions within parentheses:

27x - 18 - 6 = 20x - 5 + 2

Combine like terms on both sides:

27x - 24 = 20x - 3

Now, let's isolate the variables on one side and the constants on the other side. To do that, we'll subtract 20x from both sides:

27x - 20x - 24 = 20x - 20x - 3

7x - 24 = -3

Next, let's isolate the constant term on one side by adding 24 to both sides:

7x - 24 + 24 = -3 + 24

7x = 21

Finally, divide both sides by 7 to solve for x:

(7x) / 7 = 21 / 7

x = 3

Therefore, the solution to the given equation is x = 3.
