Помогите решить (133+x)+57=218 248-(y+128)=24 (24-x)+39=49 (y+267)-97=538 163+(87+n)=303 (x-24)-56=134

<span>(30 х Х - 560) : 8 = 80</span>

<span>30х-560=80*8</span>

<span>30х-560=640</span>

<span>30х=640=560</span>

<span>30х=1200</span>

<span>х=1200/30</span>

<span>х=40</span>

<span>630 : (30 - y) - 45 = 25</span>

<span>630/(30-у)=25+45</span>

<span>630-(30/у)=70</span>

<span>30-у=630/70</span>

<span>30-у=9</span>

<span>у=30-9</span>

<span>у=21</span>
