Question

25,12-5,12*(4,5-3y)=0,0056*380

Answer 1

25,12-5,12*(4,5-3у)=0,0056*380
25,12-5,12*(4,5-3у)=2,128
25,12-23,04+15,36у=2,128
2,08+15,36у=2,128
15,36у=2,128-2,08
15,36у=0,048
у=0,0031

Answer 2

25,12 - 5,12 * (4,5 - 3y) = 2,128
5,12 * (4,5 - 3y) = 22,992
4,5 - 3y = 4,490625
3y = 0,009375
y = 0,003125
