Question

4,5x-6,5x=-2 1,7x+10=1,5 1,7x+1,5=10 0,5x+0,5= ​

Answer 1

4,5х - 6,5х = - 2                      1,7х + 10 = 1,5

- 2х = - 2                                  1,7х = 1,5 - 10

х = - 2 : (-2)                              1,7х = - 8,5

х = 1                                         х = - 8,5 : 1,7

                                                х = - 5

--------------------------------------------------------------------

1,7х + 1,5 = 10                           0,5х + 0,5 = 1/3 + 1/6

1,7х = 10 - 1,5                            0,5х + 0,5 = 2/6 + 1/6

1,7х = 8,5                                  0,5х + 0,5 = 3/6 (=1/2)

х = 8,5 : 1,7                               0,5х = 0,5 - 0,5

х = 5                                         0,5х = 0

                                                  х = 0 : 0,5

                                                  х = 0

Answer 2

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

1. 4.5x - 6.5x = -2

Combining like terms on the left side:

-2x = -2

Dividing both sides by -2:

x = 1

2. 1.7x + 10 = 1.5

Subtracting 10 from both sides:

1.7x = 1.5 - 10 1.7x = -8.5

Dividing both sides by 1.7:

x = -5

3. 1.7x + 1.5 = 10

Subtracting 1.5 from both sides:

1.7x = 10 - 1.5 1.7x = 8.5

Dividing both sides by 1.7:

x = 5

4. 0.5x + 0.5 = ?

Subtracting 0.5 from both sides:

0.5x = -0.5

Dividing both sides by 0.5:

x = -1

Therefore, the solutions to the equations are:

1. x = 1
2. x = -5
3. x = 5
4. x = -1
