Question

4x-9=2x+116x+9=2x+335x+6=7x-10​

Answer 1

Ответ: 1) 10 2) 6 3) 8

Пошаговое объяснение:

1. 4x-9=2x+11. 2x=20; x=10

2. 6x+9=2x+33. 4x=24; x=6

3. 5x+6=7x-10. 2x=16; x=8

Answer 2

To solve these equations, you'll want to isolate the variable x in each equation. Let's go through each one step by step:

1. 4x - 9 = 2x + 11

   Start by subtracting 2x from both sides of the equation to get all the x terms on one side:

   4x - 2x - 9 = 2x - 2x + 11

   This simplifies to:

   2x - 9 = 11

   Now, add 9 to both sides to isolate x:

   2x - 9 + 9 = 11 + 9

   2x = 20

   Finally, divide both sides by 2 to find x:

   2x / 2 = 20 / 2

   x = 10

2. 6x + 9 = 2x + 33

   Start by subtracting 2x from both sides:

   6x - 2x + 9 = 2x - 2x + 33

   This simplifies to:

   4x + 9 = 33

   Now, subtract 9 from both sides to isolate x:

   4x + 9 - 9 = 33 - 9

   4x = 24

   Finally, divide both sides by 4 to find x:

   4x / 4 = 24 / 4

   x = 6

3. 5x + 6 = 7x - 10

   Start by subtracting 5x from both sides:

   5x - 5x + 6 = 7x - 5x - 10

   This simplifies to:

   6 = 2x - 10

   Now, add 10 to both sides:

   6 + 10 = 2x - 10 + 10

   16 = 2x

   Finally, divide both sides by 2 to find x:

   16 / 2 = 2x / 2

   8 = x

So, the solutions for the three equations are:

1. x = 10
2. x = 6
3. x = 8
