Question

6х-4(2х+4)=3х 5х - 11 = 8х + 3(9-2х)

Answer 1

Ответ:

Пошаговое объяснение:

6х-4(2х+4)=3х

6х- 8х-16=3х

-5х=16

х=-3,2

5х - 11 = 8х + 3(9-2х)

5х-11=8х+27-6х

3х=38

х=38/3

х=12 2/3

Answer 2

Let's solve the given equations step by step.

Equation 1: 6x - 4(2x + 4) = 3x

To solve this equation, we need to simplify and isolate the variable x.

6x - 4(2x + 4) = 3x 6x - 8x - 16 = 3x (Distribute -4) -2x - 16 = 3x (Combine like terms) -16 = 3x + 2x (Add 2x to both sides) -16 = 5x (Combine like terms) x = -16/5 (Divide both sides by 5)

So the solution to Equation 1 is x = -16/5 or -3.2.

Equation 2: 5x - 11 = 8x + 3(9 - 2x)

Similarly, let's simplify and isolate the variable x in this equation.

5x - 11 = 8x + 3(9 - 2x) 5x - 11 = 8x + 27 - 6x (Distribute 3) 5x - 11 = 2x + 27 (Combine like terms)

Now, let's isolate x by moving the constant terms to one side and the variable terms to the other side.

5x - 2x = 27 + 11 (Subtract 2x from both sides) 3x = 38 (Combine like terms) x = 38/3 (Divide both sides by 3)

So the solution to Equation 2 is x = 38/3 or approximately 12.67.

Therefore, the solutions to the given equations are: Equation 1: x = -16/5 or -3.2 Equation 2: x = 38/3 or approximately 12.67.
