Question

Решить 9х=2/5 | -3=2 7/1 | -1/2x=3 | 3/4x=1/2

Answer 1

х=2/5*9=2/45

х=9/(-3) х=-3

х=3*2/-1=-6

х=4/2*3 х=4/6 х=2/3

Answer 2

1. 9x = 2/5 To solve for x, we need to isolate it on one side of the equation. We can do that by dividing both sides by 9: 9x/9 = 2/5/9 x = 2/5 ÷ 9 x = 2/5 * 1/9 x = 2/45

   Therefore, the solution is x = 2/45.

2. -3 = 2 7/1 This is already in its simplest form, so there is no further simplification needed. The solution is -3 = 2 7/1.

3. -1/2x = 3 To solve for x, we need to isolate it on one side of the equation. We can do that by multiplying both sides by -2: -2 * -1/2x = -2 * 3 x = -6/-2 x = 3

   Therefore, the solution is x = 3.

4. 3/4x = 1/2 To solve for x, we need to isolate it on one side of the equation. We can do that by multiplying both sides by 4/3: 4/3 * 3/4x = 4/3 * 1/2 x = 2/3

   Therefore, the solution is x = 2/3.
