Question

-17х+2х= х-2х= -10-2t+15= 5-у+2у-3= 3/7х+5/56х= -2/3б+5/12б= -4/25а-2/5а=

Answer 1

Ответ:

-15х

-х

5-2t

y+2

29/56х

-1/4b

-14/25a

Пошаговое объяснение:

-17х+2х=-15х

х-2х=-х

-10-2t+15=5-2t

5-y+2y-3=y+2

3/7х+5/56х=(24+5)/56х=29/56х

-2/3b+5/12b=(-8+5)/12b=-3/12b=-1/4b

-4/25a-2/5a=(-4-10)/25a=-14/25a

Answer 2

It looks like you've provided a series of equations and expressions. It seems there might be some errors in the equations, as some of them seem incomplete or have missing operators. I'll try to interpret what you've written, correct any obvious mistakes, and solve for the variables where possible.

1. Equation 1: -17x + 2x = x - 2x This equation simplifies to -15x = -x, which further simplifies to x = 0.

2. Equation 2: -10 - 2t + 15 = 5 - у + 2у - 3 Combine the numbers: -10 + 15 = 5 - 3, which simplifies to 5 = 2. The equation 5 = 2 is not true, so there seems to be an inconsistency in the equation.

3. Equation 3: 3/7x + 5/56x = -2/3б + 5/12б This equation involves fractions and variables, but the variable "б" is used, which is not a standard English letter. If you meant "b," then the equation could be simplified and solved for "x" and "b."

   To solve this equation, let's first find a common denominator for the fractions involving "x":

   (3/7 + 5/56)x = (-2/3 + 5/12)b (24/56 + 5/56)x = (20/12 - 10/12)b (29/56)x = (10/12)b

   Now, let's solve for "x":

   x = (10/12 * 56/29)b x = (280/348)b x ≈ 0.8046b

4. Equation 4: -4/25а - 2/5а = ? It seems like there's a missing part of the equation or an operator. If you meant to solve this equation, please provide the complete equation.

5. Equation 5: Missing equation or incomplete expression. It's unclear what you're asking here.

If you could provide more context or clarify the equations, I would be happy to help you further.
