Question

7(х-1)-3(х+2)+6=6-(2х+1)

Answer 1

Ответ: 4х-7=7-2х

Объяснение:

• 7(х-1)-3(х+2)+6=6-(2х+1)

• 7х-7-3х-6+6=6-2х+1 (розкриємо дужки)

• 7х-7-3х=6-2х+1 (показуємо, що 6 і (-6) можемо знищити)

• 4х-7=7-2х (зводимо подібні)

Answer 2

To solve this equation for the variable x, follow these steps:

1. Distribute the numbers outside the parentheses to the terms inside: 7(x - 1) - 3(x + 2) + 6 = 6 - (2x + 1) 7x - 7 - 3x - 6 + 6 = 6 - 2x - 1

2. Combine like terms on both sides of the equation: (7x - 3x) + (-7 - 6 + 6) = 6 - 2x - 1 4x - 7 = 5 - 2x

3. Add 2x to both sides of the equation to isolate the variable terms on one side: 4x + 2x - 7 = 5 - 2x + 2x 6x - 7 = 5

4. Add 7 to both sides of the equation to solve for x: 6x - 7 + 7 = 5 + 7 6x = 12

5. Finally, divide both sides by 6 to solve for x: x = 12 / 6 x = 2

So, the solution to the equation is x = 2.
