Question

Как решить уравнение 8 икс минус 5 икс минус 3 равно 6. и сделать проверку

Answer 1

8x-5x-3 = 6
8x-5x = 6+3 (перенос знака)
3x = 9
x = 3
Проверка:
8*3-5*3-3 = 6
24 - 15 - 3 = 6
( * - это знак умножить)

Answer 2

Solving the Equation 8x - 5x - 3 = 6

To solve the equation 8x - 5x - 3 = 6, we can follow these steps:

1. Combine like terms on the left side of the equation. 2. Solve for the variable x.

Solution Steps

1. Combine Like Terms: - 8x - 5x - 3 = 6 - (8 - 5)x - 3 = 6 - 3x - 3 = 6

2. Isolate the Variable: - Add 3 to both sides of the equation to isolate the variable x. - 3x - 3 + 3 = 6 + 3 - 3x = 9

3. Solve for x: - Divide both sides by 3 to solve for x. - 3x / 3 = 9 / 3 - x = 3

Verification

To verify the solution, we substitute the value of x back into the original equation and check if both sides are equal.

Original Equation: 8x - 5x - 3 = 6 Substitute x = 3: 8(3) - 5(3) - 3 = 6 24 - 15 - 3 = 6 6 = 6

The verification shows that both sides are equal when x = 3, confirming that the solution is correct.
