Ответ:

$x = 2 \\ x = 10$

............

Answer 2

Пошаговое объяснение:

A) 3x+6-x=10

2x+6=10

2x=10-6

2x=4

x=4/2=2

Б) 3x-12-x=8

2x-12=8

2x=8+12

2x=20

x=10

Answer 3

Let's solve each equation step by step:

A) 3(x + 2) - x = 10

First, distribute the 3 to both terms inside the parentheses: 3x + 6 - x = 10

Combine like terms: 2x + 6 = 10

Next, isolate the variable term by subtracting 6 from both sides: 2x = 10 - 6 2x = 4

Finally, divide both sides by 2 to solve for x: x = 4 / 2 x = 2

Therefore, the solution to equation A is x = 2.

B) 3(x - 4) - x = 8

Again, distribute the 3 to both terms inside the parentheses: 3x - 12 - x = 8

Combine like terms: 2x - 12 = 8

Next, isolate the variable term by adding 12 to both sides: 2x = 8 + 12 2x = 20

Finally, divide both sides by 2 to solve for x: x = 20 / 2 x = 10

Therefore, the solution to equation B is x = 10.
