Пошаговое объяснение:

1) x = -3,51 : (-2,6) = 1,35

2) x = 10,64 : (-1,4) = -7,6

3) x = 1,17 : (-0,18) = -6,5

4) x = -18,06 : 4,2 = -4,3

5)  24x * (-7) = 5 * 48

-168x = 240

x = 240/ (-168)

x = -10/7

6)x = -14/15 * (-7)

x = 2/15

Answer 2

To solve each of these equations, you can isolate the variable (x) by performing the necessary operations to both sides of the equation. Here's how you can solve each equation:

1. -2 * 6x = -3.51

   Divide both sides by -2: 6x = -3.51 / -2 6x = 1.755

   Now, divide by 6 to isolate x: x = 1.755 / 6 x ≈ 0.2925

2. 10.64 / x = -1.4

   Divide both sides by 10.64: 10.64 / x = -1.4

   Now, isolate x by taking the reciprocal of both sides: x = 10.64 / (-1.4) x ≈ -7.6

3. -0.18x = 1.17

   Divide both sides by -0.18: x = 1.17 / -0.18 x ≈ -6.5

4. -18.06 / x = 4.2

   Divide both sides by -18.06: -18.06 / x = 4.2

   Now, isolate x by taking the reciprocal of both sides: x = -18.06 / 4.2 x ≈ -4.3

5. (5/24)x = -7/48

   Multiply both sides by 24 to isolate x: x = (-7/48) * 24 x = -7/2 x = -3.5

6. (-14/15) / x = -7

   Multiply both sides by x to isolate x: -14/15 = -7x

   Now, divide both sides by -7 to solve for x: (1/15) * 14 = x x = 14/15
