Question

Решите уравнения
3x+5x+96=1568
357z-149z-1843=11469
2y+7y+78=1581
256m-147m-1871=63747

Answer 1

1)3х+5х+96=1568
8х+96=1568
8х=1568-96
8х=1472
х=1472:8
х=184
2)357z-149z-1843=11469
208z=11469+1843
208z=13312
z=64
3)2у+7у+78=1581
9у+78=1581
9у=1581-78
9у=1503
у=1503:9
у=167
4)256m-147m-1871=63747
109m-1871=63747
109m=63747+1871
109m=65618
m=65618:109
m=602

Answer 2

8x+96=1558=>8x=1558-96=>8x=1462=> 1462:8=182.75
