Answer 1

1. х+2у-3=2х+у+2                                 2(х+у-1)=х+2
    х-2х+2у-у=2+3                                 2х+2у-2=х+2
у-х=5                                                2х-х+2у=2+2
у=5+х                                                х+2у=4
у=5-2                                                 х+2(5-2)=4
у=3                                                    х+10+2х=4
                                                          3х=-6
                                                          х=-2
