Question

-3 * (12 - 2x) = 4x - 30

Answer 1

Ответ:

х=3

Пошаговое объяснение:

-3 * (12 - 2x) = 4x - 30

-36 + 6х =4х-30

6х - 4х =-30 +36

2х=6

х=6:2

х=3

--------------------

-3*(12-2*3)=4*3 - 30

-3*6=12-30

-18 = -18

Answer 2

-3 * (12 - 2x) = 4 x - 30
-36 ÷ 6× =4x-30
6× - 4x =-30 +36
2x=6
X=6:2
X=3
-3* (12-2*3)=4×3 - 30
-3*6=12-30
-18 = -18

Answer 3

To solve the equation -3 * (12 - 2x) = 4x - 30 for the variable x, you'll need to follow these steps:

1. Distribute the -3 on the left side of the equation by multiplying it with each term inside the parentheses:

-3 * 12 + 3 * 2x = 4x - 30

2. Simplify both sides of the equation by performing the multiplications:

-36 + 6x = 4x - 30

3. Next, isolate the variable terms (terms with x) on one side and the constant terms on the other side of the equation. You can do this by moving 4x from the right side to the left side of the equation by subtracting 4x from both sides:

-36 + 6x - 4x = -30

Simplifying further:

2x - 36 = -30

4. Now, add 36 to both sides of the equation to isolate the 2x term:

2x - 36 + 36 = -30 + 36

Simplifying:

2x = 6

5. Finally, divide both sides by 2 to solve for x:

(2x)/2 = 6/2

x = 3

So, the solution to the equation -3 * (12 - 2x) = 4x - 30 is x = 3.
