Question

9-6(7-5х)=8+2(х+4) Решите пожалуйста Заранее спасибо

Answer 1

9-6(7-5х)=8+2(х+4)
9-42+30х=8+2х+8
30х-33=2х+16
30х-2х=16+33
28х=49
х=49:28
х=1,75

Answer 2

Solving the Equation

To solve the equation 9 - 6(7 - 5x) = 8 + 2(x + 4), we can follow these steps:

Step 1: Simplify both sides of the equation by applying the distributive property and combining like terms.

On the left side: 9 - 6(7 - 5x) = 9 - 42 + 30x

On the right side: 8 + 2(x + 4) = 8 + 2x + 8

Simplifying further: 9 - 42 + 30x = 8 + 2x + 8

Step 2: Combine like terms on both sides of the equation.

On the left side: -33 + 30x

On the right side: 2x + 16

So the equation becomes: -33 + 30x = 2x + 16

Step 3: Move all the terms with x to one side of the equation and the constant terms to the other side.

-33 + 30x - 2x = 16

Simplifying further: 28x - 33 = 16

Step 4: Solve for x.

To solve for x, we need to isolate the variable on one side of the equation. Let's move the constant term to the other side.

28x = 16 + 33

Simplifying further: 28x = 49

Finally, divide both sides of the equation by 28 to solve for x:

x = 49/28

Therefore, the solution to the equation is x = 49/28.
