Question

Решите уровнение:2(x-3)-3(x-10)=5

Answer 1

Ответ:

19

Пошаговое объяснение:

2x - 6 - 3x + 30 = 5

-x = 5 - 24

-x = -19

x = 19

проверка:

2(19 - 3) - 3(19 - 10) = 5

2 * 16 - 3 * 9 = 5

32 - 27 = 5

5 = 5

верно

Answer 2

2(x-3)-3(x-10) = 5

Раскрываем скобки:

2x-6-3x+30-5 = 0

-x-19 = 0

x = 19

Answer 3

To solve the equation 2(x-3) - 3(x-10) = 5, follow these steps:

Step 1: Distribute the coefficients inside the parentheses. Step 2: Combine like terms on both sides of the equation. Step 3: Isolate the variable (x) on one side of the equation. Step 4: Solve for x.

Let's go through each step:

Step 1: Distribute the coefficients inside the parentheses. 2(x-3) - 3(x-10) = 5

Distribute the 2 and the -3: 2x - 6 - 3x + 30 = 5

Step 2: Combine like terms on both sides of the equation. Combine the x terms and the constants on the left side: (2x - 3x) + (30 - 6) = 5

Simplify: -x + 24 = 5

Step 3: Isolate the variable (x) on one side of the equation. To isolate x, we need to move 24 to the other side of the equation. Since 24 is positive on the left side, we'll subtract 24 from both sides of the equation to cancel it out:

-x + 24 - 24 = 5 - 24

Simplify: -x = -19

Step 4: Solve for x. To find the value of x, multiply both sides by -1 to remove the negative sign in front of x:

(-1)(-x) = (-1)(-19)

Simplify: x = 19

The solution to the equation is x = 19.
