Question

4(-3-2y)-30=2(-3+2y)-решите уравнение

Answer 1

4(-3-2y)-30=2(-3+2y)
-12 - 8у - 30 = -6 + 4у
-8у - 4у = -6 + 12 + 30
-12у = 36
у = 36 ÷ (-12)
у = -3.
Ответ : у = -3.

Удачи))))

Answer 2

To solve the equation 4(-3-2y) - 30 = 2(-3+2y), follow these steps:

Step 1: Distribute the terms on both sides of the equation. Step 2: Combine like terms. Step 3: Isolate the variable on one side of the equation. Step 4: Solve for the variable.

Let's go through each step:

Step 1: 4 * (-3) + 4 * (-2y) - 30 = 2 * (-3) + 2 * 2y

Step 2: -12 - 8y - 30 = -6 + 4y

Step 3: Now, we want to isolate the variable (y) on one side of the equation. To do that, we'll move all the terms with y to the left side by adding 8y to both sides and move the constant terms to the right side by adding 6 to both sides:

-12 - 8y - 30 + 8y = -6 + 4y + 8y

Simplifying further:

-12 - 30 = -6 + 12y

Step 4: Combine the constants on the left side:

-42 = -6 + 12y

Now, isolate the variable y by moving the constant term (-6) to the left side:

-42 + 6 = 12y

Combine constants:

-36 = 12y

Finally, solve for y by dividing both sides by 12:

y = -36 / 12

y = -3

So, the solution to the equation is y = -3.
