1) 3 х + 5 х + 96 = 1568;

3 х + 5 х = 1568 - 96;

8 х = 1472;

х = 1472 : 8;

х = 184.

2) 357z - 149z - 1843 = 11469;

357z - 149z = 11469 + 1843;

208z = 13312;

z = 13312 : 208;

z = 64.

3) 2y + 7y + 78 = 1581;

2y + 7y = 1581 - 78;

9y = 1503;

y = 1503 : 9;

y = 167.

4) 256m - 147m - 1871 = 63747;

256m - 147m = 63747 + 1871;

109m = 65618;

m = 65618 : 109;

m = 602.

5) 88880/110 + x = 809;

808 + x = 809;

x = 809 - 808;

x = 1.

6) 6871 + p/121 = 7000;

p/121 = 7000 - 6871;

p/121 = 129;

p = 129 * 121;

p = 15609.

7) 3810 + 1206/y = 3877;

1206/y = 3877 - 3810;

1206/y = 67;

1206 = 67y;

y = 1206 : 67;

y = 18.

8) k + 12705/121 = 105;

k + 105 = 105;

k = 105 - 105;

k = 0.
