Answer 1

Ответ:

$- 3x + 4 = - 17 \\ 3x = 21 \\ x = 7 \\ \\ 4x + 10 = 2x - 2 \\ 2x = - 12 \\ x = - 6 \\ \\ - 5x + 3 = - x + 23 \\ 4x = - 20 \\ x = - 5$

Answer 2

To solve these equations for the variable "x," you'll need to isolate "x" on one side of the equation. Let's go through each of them:

1. -3x + 4 = -17

   Start by subtracting 4 from both sides of the equation:

   -3x + 4 - 4 = -17 - 4

   -3x = -21

   Now, divide both sides by -3 to isolate "x":

   (-3x) / (-3) = (-21) / (-3)

   x = 7

2. 4x + 10 = 2x - 2

   Start by subtracting 2x from both sides of the equation:

   4x - 2x + 10 = 2x - 2 - 2x

   2x + 10 = -2

   Next, subtract 10 from both sides:

   2x + 10 - 10 = -2 - 10

   2x = -12

   Now, divide both sides by 2 to isolate "x":

   (2x) / (2) = (-12) / (2)

   x = -6

3. -5x + 3 = -x + 23

   Start by adding "x" to both sides of the equation to move all "x" terms to one side:

   -5x + x + 3 = -x + x + 23

   -4x + 3 = 23

   Next, subtract 3 from both sides:

   -4x + 3 - 3 = 23 - 3

   -4x = 20

   Finally, divide both sides by -4 to isolate "x":

   (-4x) / (-4) = 20 / (-4)

   x = -5

So, the solutions to the equations are:

1. x = 7
2. x = -6
3. x = -5

Answer 3

Let's solve each of these equations step by step:

1. -3x + 4 = -17

   First, subtract 4 from both sides of the equation:

   -3x + 4 - 4 = -17 - 4

   -3x = -21

   Now, divide both sides by -3 to isolate x:

   (-3x) / (-3) = (-21) / (-3)

   x = 7

So, the solution to the first equation is x = 7.

2. 4x + 10 = 2x - 2

   First, subtract 2x from both sides of the equation:

   4x - 2x + 10 = 2x - 2 - 2x

   2x + 10 = -2

   Now, subtract 10 from both sides:

   2x + 10 - 10 = -2 - 10

   2x = -12

   Finally, divide both sides by 2 to isolate x:

   (2x) / 2 = (-12) / 2

   x = -6

So, the solution to the second equation is x = -6.

3. -5x + 3 = -x + 23

   First, add x to both sides of the equation:

   -5x + 3 + x = -x + 23 + x

   -4x + 3 = 23

   Now, subtract 3 from both sides:

   -4x + 3 - 3 = 23 - 3

   -4x = 20

   Finally, divide both sides by -4 to isolate x:

   (-4x) / (-4) = 20 / (-4)

   x = -5

So, the solution to the third equation is x = -5.

Therefore, the solutions to the given equations are:

1. x = 7
2. x = -6
3. x = -5
