Question

Алгебра: 3. 3x - 7 = 4(2x - 3) - 54.17 - 2(6x – 5) = 4(7x - 2)5. 6x - 3(5x + 4) - 2(7x - 3) = -66.-2(x+21)-3(x - 14) = -5xрешите ​

ответ: 3х-7=8х-12-53х-8х=-12-5+7-5х=-10х=26х-3 (5х+4)-2(7х-3)=-66х-15-12-14х+6=-66х-14х=-6+15+12-6-8х=15х=-1,875дальше извини сама уроки делаю...

3. 3x - 7 = 4(2x - 3) - 5
4.17 - 2(6x – 5) = 4(7x - 2)
5. 6x - 3(5x + 4) - 2(7x - 3) = -6
6.-2(x+21)-3(x - 14) = -5x
