Question

- 9 (8 - 9х) = 4х + 5 помогите плиззз

Answer 1

-72+81x = 4x+5
81x -4x = 5+72
77x = 77, x=1

Answer 2

Solving the Equation

To solve the equation 9 + (8 - 9x) = 4x + 5, we can follow these steps:

1. Combine Like Terms: Combine the constants and the terms with x on one side of the equation and the constants on the other side. 2. Simplify: Simplify the equation to solve for x.

Let's solve the equation step by step.

Step 1: Combine Like Terms

First, let's combine the constants and the terms with x on one side of the equation and the constants on the other side.

9 + (8 - 9x) = 4x + 5

9 + 8 - 9x = 4x + 5

Step 2: Simplify

Now, let's simplify the equation to solve for x.

17 - 9x = 4x + 5

Step 3: Solve for x

To solve for x, we can start by moving the terms with x to one side of the equation and the constants to the other side.

17 - 9x - 4x = 5

17 - 13x = 5

Step 4: Continue Simplifying

Next, we can continue simplifying the equation.

-13x = 5 - 17

-13x = -12

Step 5: Solve for x

Finally, we can solve for x by dividing both sides of the equation by -13.

x = -12 / -13

x = 12 / 13

So, the solution to the equation 9 + (8 - 9x) = 4x + 5 is x = 12/13.
