Question

4/9y+1/3y=6,3найдите пожалусто

Answer 1

4/9у+1/3у=6,3
4/9у+3/9у=6,3
7/9у=6,3
у=6,3:7/9
у=6,3*9/7
у=8,1

Answer 2

To solve this equation, we need to first simplify the left-hand side by finding a common denominator for the two fractions:

4/9y + 1/3y = (4/9) * (3/3y) + (1/3) * (3/3y) = 12/27y + 3/27y = 15/27y = 5/9y

Now we can substitute this back into the original equation:

5/9y = 6,3

To isolate y, we can multiply both sides by 9y:

5 = 6,3 * 9y

Dividing both sides by 6.3*9, we get:

y = 5 / (6.3 * 9)

y ≈ 0.0952

Therefore, the solution to the equation is y ≈ 0.0952.
