Question

-4х-2= -13+21 5у=2у+15 3х+8=х-12 х+4-3=2х -2х+9-8= -х-1

Answer 1

Если не понятно пиши

Answer 2

Ответ:

-4x-2= -13+21

-4x = 2-13+21

-4x = 10

x= -4:10

x = -0.4

Answer 3

It looks like you've provided a list of equations. Let's solve them one by one:

1. -4x - 2 = -13 + 21 Simplifying both sides: -4x - 2 = 8 Adding 2 to both sides: -4x = 10 Dividing by -4: x = -2.5

2. 5y = 2y + 15 Subtracting 2y from both sides: 3y = 15 Dividing by 3: y = 5

3. 3x + 8 = x - 12 Subtracting x from both sides: 2x + 8 = -12 Subtracting 8 from both sides: 2x = -20 Dividing by 2: x = -10

4. x + 4 - 3 = 2x Simplifying: x + 1 = 2x Subtracting x from both sides: 1 = x

5. -2x + 9 - 8 = -x - 1 Simplifying: -2x + 1 = -x - 1 Adding 2x to both sides: 1 = x - 1 Adding 1 to both sides: 2 = x

So, the solutions are:

1. x = -2.5
2. y = 5
3. x = -10
4. x = 1
5. x = 2
