Question

Рівняння 6клас: (7х+1)-(9х+3)=5

Answer 1

Ответ:

x = -3,5

Пошаговое объяснение:

(7x+1) - (9x+3) = 5

7x + 1 - 9x - 3 = 5

7x - 9x = 5 - 1 + 3

-2x = 7

x = -3,5

Answer 2

To solve the equation (7x+1)-(9x+3)=5, follow these steps:

Step 1: Simplify the equation by removing the parentheses. (7x + 1) - (9x + 3) = 5

To do this, distribute the negative sign through the parentheses: 7x + 1 - 9x - 3 = 5

Step 2: Combine like terms on the left side of the equation. (7x - 9x) + (1 - 3) = 5

Simplify further: -2x - 2 = 5

Step 3: Isolate the variable (x) on one side of the equation. To do this, we need to get rid of the constant term on the left side. We can do this by adding 2 to both sides of the equation.

-2x - 2 + 2 = 5 + 2

Simplify: -2x = 7

Step 4: Finally, solve for x by dividing both sides of the equation by -2.

x = 7 / (-2)

x = -3.5

So, the solution to the equation is x = -3.5.
