Question

5m-4n-3m+2n= 1/12p-1/3p-1/4p=-2x+3y-3x+5y= 0,12a-0,48a-0,37a=12,9b+13,7c-4,5b=расписать решение

Answer 1

1) 5m-4n-3m+2n = 5m-3m-4n+2n = 2m-2n = 2(m-n)

2) 1/12p-1/3p-1/4p= 1/12p-4/12p-3/12p =1/12p-7/12p= -6/12p = -1/2p

3) -2x+3y-3x+5y = -2x-3x+3y+5y = -5x+8y

4) 0,12a-0,48a-0,37a = 0,12-0,85a = -0,73

5) 12,9b+13,7c-4,5b= 12,9b-4,5b+13,7c = 8,4b+13,7c

Answer 2

To solve the given equations, we will simplify and solve each equation step-by-step. Let's start:

1. 5m - 4n - 3m + 2n = 0 Combine like terms on both sides of the equation: (5m - 3m) + (-4n + 2n) = 0 2m - 2n = 0

2. 1/12p - 1/3p - 1/4p = 0 Find a common denominator for the fractions: (4 - 16 - 3)p / 12p = 0 (-19p) / 12p = 0 Divide both sides by "p" (assuming p ≠ 0): -19 / 12 = 0

However, there seems to be an issue with this equation as there is no solution that satisfies this equation. The variable "p" seems to have canceled out in the equation, and we are left with an untrue statement. Please double-check the equation and ensure there are no typographical errors.

3. -2x + 3y - 3x + 5y = 0 Combine like terms on both sides of the equation: (-2x - 3x) + (3y + 5y) = 0 -5x + 8y = 0

4. 12a - 0.48a - 0.37a = 0 Combine like terms on both sides of the equation: (12a - 0.48a - 0.37a) = 0 (12a - 0.85a) = 0 11.15a = 0

Divide both sides by 11.15 (assuming a ≠ 0): a = 0

5. 12.9b + 13.7c - 4.5b = 0 Combine like terms on both sides of the equation: (12.9b - 4.5b) + 13.7c = 0 8.4b + 13.7c = 0

Now, we have solved all the equations as much as possible. The solutions are:

1. 2m - 2n = 0
2. -19 / 12 = 0 (Please verify this equation)
3. -5x + 8y = 0
4. a = 0
5. 8.4b + 13.7c = 0

Please recheck the equation involving "p" to ensure its accuracy, and let me know if there are any other specific instructions or questions you have regarding the solutions.
