Question

Решить уравнение (x+7)*2-10=20​

Answer 1

(х+7)*2 - 10 = 20

(х+7)*2 = 30

(х+7) = 30/2

х+7 = 15

х = 8

ОТВЕТ: 8

Answer 2

(х+7)*2-10=20

2х+14-10=20

2х=20-14+10

2х=16

х=8

Answer 3

To solve the equation, follow these steps:

Step 1: Simplify the equation. Step 2: Isolate the variable (x) on one side of the equation. Step 3: Solve for x.

Let's proceed with solving the equation:

Step 1: Simplify the equation. First, distribute the 2 on the left side of the equation:

2 * (x + 7) - 10 = 20

Step 2: Isolate the variable (x) on one side of the equation. Next, get rid of the constant term (-10) on the left side by adding 10 to both sides:

2 * (x + 7) = 20 + 10 2 * (x + 7) = 30

Step 3: Solve for x. Now, to isolate x, divide both sides by 2:

(x + 7) = 30 / 2 (x + 7) = 15

Finally, isolate x by subtracting 7 from both sides:

x = 15 - 7 x = 8

So, the solution to the equation is x = 8.
