Answer 1

Ответ:

Пошаговое объяснение:

1) -6x + 5 = -2x

-4x=-5

x=5/4

2) 9x +4 = 48 - 2x

11x=44

x=4

3) 4(x - 6) = x - 9

4x-24=x-9

3x=15

x=5

5) (8x + 3) - (10x+6) =9

8x+3-10x-6=9

-2x=12

x=-6

6) 5(х-12) =6(х-10) -х

5x-60=6x-60-x

5x=5x

1=1

Answer 2

It seems like you've provided a set of equations. Do you need help solving them? I'd be happy to assist! Let's solve each equation step by step:

1. -6x + 5 = -2x Subtract -2x from both sides: -6x + 2x + 5 = 0 -4x + 5 = 0 Subtract 5 from both sides: -4x = -5 Divide by -4: x = 5/4 or 1.25

2. 9x + 4 = 48 - 2x Add 2x to both sides: 9x + 2x + 4 = 48 11x + 4 = 48 Subtract 4 from both sides: 11x = 44 Divide by 11: x = 4

3. 4(x - 6) = x - 9 Distribute the 4 on the left side: 4x - 24 = x - 9 Subtract x from both sides: 4x - x - 24 = -9 3x - 24 = -9 Add 24 to both sides: 3x = 15 Divide by 3: x = 5

4. (8x + 3) - (10x + 6) = 9 Distribute the negative sign on the right parentheses: 8x + 3 - 10x - 6 = 9 Combine like terms: -2x - 3 = 9 Add 3 to both sides: -2x = 12 Divide by -2: x = -6

5. 5(x - 12) = 6(x - 10) - x Distribute the 5 and 6 on the respective sides: 5x - 60 = 6x - 60 - x Combine like terms: 5x - 60 = 5x - 60 Subtract 5x from both sides: -60 = -60 This equation is true for any value of x. It means that the equation has infinitely many solutions, and any value of x will satisfy it.
