Answer 1

Ответ:

8x-20-45-9x=6x+12

8x-9x-6x=20+12+45

-7x=77

X=77:(-7)

X=-11

Answer 2

Ответ:

8х-20-45+9х=6х+12

8х+9х-6х=20+45+12

11х=77

х=7

Answer 3

To solve the equation 4×(2х-5)-9×(5-х)=6×(х+2), let's simplify and solve step by step:

Step 1: Distribute the multiplication on both sides of the equation: 4×2х - 4×5 - 9×5 + 9×х = 6×х + 6×2

Simplifying this equation gives: 8х - 20 - 45 + 9х = 6х + 12

Step 2: Combine like terms on both sides of the equation: 17х - 65 = 6х + 12

Step 3: Move all the terms involving х to one side of the equation: 17х - 6х = 12 + 65

Simplifying: 11х = 77

Step 4: Divide both sides of the equation by 11 to solve for х: 11х/11 = 77/11

Simplifying: х = 7

Therefore, the solution to the equation 4×(2х-5)-9×(5-х)=6×(х+2) is х = 7.
