Question

12-4(x-3) = 39 - 9xсрочно 25 баллов

Answer 1

$12 - 4x + 12 - 39 + 9x = 0 \\ 5x = 15 \\ x = 3$

Answer 2

12-4(х-3)=39-9х
12-4х-7=39-9х
-4х+9х=39-12+7
5х=34
х=34÷5
х=6,8

Answer 3

To solve the equation 12 - 4(x - 3) = 39 - 9x, follow these steps:

Step 1: Distribute the -4 on the left side of the equation: 12 - 4x + 12 = 39 - 9x

Step 2: Combine like terms on the left side: 24 - 4x = 39 - 9x

Step 3: Get all the x terms on one side of the equation. To do this, add 9x to both sides: 24 + 5x = 39

Step 4: Now, isolate the x term by subtracting 24 from both sides: 5x = 39 - 24 5x = 15

Step 5: Finally, solve for x by dividing both sides by 5: x = 15 / 5 x = 3

So, the solution to the equation is x = 3.
