Question

3 3/7х-(1 3/14х+8/21х)= ЕСЛИ х = 2/11

Answer 1

3 3/7*2/11-(1 3/14+8/21*2/11)=24/7*2/11-(17/14+16/231)=48/77-593/462= -305/462

Answer 2

To solve the equation 3 3/7х-(1 3/14х+8/21х) = y, where x = 2/11, we first need to simplify the expression on the left-hand side:

3 3/7х - (1 3/14х + 8/21х) = (24/7 + 3/7) * (2/11) - (16/14 + 8/21) * (2/11) [convert mixed numbers to improper fractions] = (27/7) * (2/11) - (32/21) * (2/11) = 54/77 - 64/231 = 118/231

Therefore, when x = 2/11, the equation 3 3/7х-(1 3/14х+8/21х) equals 118/231.

So, the solution to the equation is y = 118/231.
