Question

(3x-5)=2+(7-4x) .....

Answer 1

(3х - 5) = 2 + (7 - 4х)

3х - 5 = 2 + 7 - 4х

3х + 4х = 9 + 5

7х = 14

х = 14 : 7

х = 2

Проверка:

(3·2 - 5) = 2 + (7 - 4·2)

6 - 5 = 2 + (7 - 8)

1 = 2 - 1

1 = 1

Answer 2

Ответ:

x=2

Пошаговое объяснение:3x-5=2+7-4x

3x+4x=9+5

7x=14

x=2

Answer 3

To solve the equation (3x - 5) = 2 + (7 - 4x), follow these steps:

Step 1: Distribute the parentheses on the right side of the equation: (3x - 5) = 2 + 7 - 4x

Step 2: Combine like terms on the right side: (3x - 5) = 9 - 4x

Step 3: Move all the x terms to one side of the equation by adding 4x to both sides: (3x + 4x) - 5 = 9 - 4x + 4x

Simplifying the left side and canceling the -4x and +4x on the right side: 7x - 5 = 9

Step 4: Now, isolate x by adding 5 to both sides of the equation: 7x - 5 + 5 = 9 + 5

Simplifying: 7x = 14

Step 5: Finally, divide both sides by 7 to solve for x: x = 14 / 7

Simplifying: x = 2

So the solution to the equation is x = 2.
