3(x-1)=2(2-x)+6госпади​

Answer 1

Ответ:

3(x-1)=2(2-x)+6

Раскрываем скобки «фонтанчиком»

3*х+3*(-1)=2*2+2*(-х)+6

3х-3=4-2х+6

3х+2х=4+6+3

5х=13

х=13/5=2 3/5=2,6

Проверка:

3(2,6-1)=2(2-2,6)+6

3*1,6=2*(-0,6)+6

4,8=-1,2+6

4,8=4,8

Answer 2

To solve the equation 3(x-1) = 2(2-x) + 6, we'll simplify the equation step by step:

1. Distribute the multiplication on both sides: 3x - 3 = 4 - 2x + 6

2. Combine like terms: 3x - 3 = -2x + 10

3. Add 2x to both sides to isolate the x terms on one side: 5x - 3 = 10

4. Add 3 to both sides to move the constant term to the other side: 5x = 13

5. Divide both sides by 5 to solve for x: x = 13/5

Therefore, the solution to the equation 3(x-1) = 2(2-x) + 6 is x = 13/5 or 2.6.
