Ответ:
ну...например 1.32; 1.34; 1.36; 1.37; 1.39;
4х+3/4-2х+2/4=1
2х+5/4=1
2х=1-5/4
2х=-1/4
х=-1/8
= a^-15/a^-13 = 1/a^2
1/a^2 = 1/ 1/2 = 1/1 / 1/2 = 1*2 / 1*1 = 2
{х+2у+2у=11
{<span>5х-3у=3
</span><span>{х+4у=11 /х3
</span><span>{5х-3у=3 /х4
</span><span>{3х+12у=33
</span>20х-12у=12
23х=45
х=45/23
5(45/23)-3у=3
225/23-3у=3
-3у=3-225/23
-3у=-156/23
3у=156/23
у=52/23
