Question

- 4/7 y = 8/21 Решите уравнение

Answer 1

4\7у=8\21

у=8\21:(-4-7)

у=8\21*(-7\4)

у=2\3*(-1\1):-2\3

Answer 2

To solve the equation (-4/7)y = 8/21, you need to isolate y on one side of the equation. Follow these steps:

Step 1: Get rid of the fraction coefficient (-4/7) by multiplying both sides of the equation by the reciprocal of (-4/7), which is -7/4. This will cancel out the fraction on the left side.

(-7/4) * (-4/7) * y = (-7/4) * (8/21)

Step 2: Simplify both sides of the equation.

y = (-7/4) * (8/21)

Step 3: Continue simplifying.

y = -56/84

Step 4: Reduce the fraction to its simplest form.

y = -2/3

So the solution to the equation is y = -2/3.
