Answer 1

Ответ в приложении. Удачи.

Answer 2

1) x = 2+4

   x = 6

2) y = 3-5

   y = -2

3) 3-x = 1,5

    -x = 1,5-3

    -x = -1,5

    x = 1,5

4)  7-y = -2

     -y = -2 - 7

      -y = -9

       y=9

5) x+3+4 = 9

    x = 9 - 3 -4

    x = 2

6) y-2+8=5

    y = 5+2-8

    y = -1

Answer 3

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

1. x - 4 = 2 To solve for x, we need to isolate it on one side of the equation. Adding 4 to both sides: x - 4 + 4 = 2 + 4 x = 6

2. y + 5 = 3 To solve for y, we need to isolate it on one side of the equation. Subtracting 5 from both sides: y + 5 - 5 = 3 - 5 y = -2

3. 3 - x = 1.5 To solve for x, we need to isolate it on one side of the equation. Subtracting 3 from both sides: 3 - x - 3 = 1.5 - 3 -x = -1.5 Multiplying both sides by -1 to isolate x: (-1)(-x) = (-1)(-1.5) x = 1.5

4. 7 - y = -2 To solve for y, we need to isolate it on one side of the equation. Subtracting 7 from both sides: 7 - y - 7 = -2 - 7 -y = -9 Multiplying both sides by -1 to isolate y: (-1)(-y) = (-1)(-9) y = 9

5. x + 3 + 4 = 9 Combining like terms: x + 7 = 9 To solve for x, we need to isolate it on one side of the equation. Subtracting 7 from both sides: x + 7 - 7 = 9 - 7 x = 2

6. y - 2 + 8 = 5 Combining like terms: y + 6 = 5 To solve for y, we need to isolate it on one side of the equation. Subtracting 6 from both sides: y + 6 - 6 = 5 - 6 y = -1

The solutions to the given equations are:

1. x = 6
2. y = -2
3. x = 1.5
4. y = 9
5. x = 2
6. y = -1
