1. 17x-8=20x+7

17x-20x=7+8

-3x=15

x=5

2. х кг- младший,

3х кг-старший,

(х+13) кг -средний.

Всего- 88 кг яблок.

х+3х+х+13=88

5х=88-13

5х=75

х=75:5

х=15(кг)- яблок собрал младший брат.

3.   0,6(х+2)+4,6=0,4(7+х)

0,6x + 1,2+4=2,8+0,4x

     0,6x+5,2=2,8+0,4x

     0,6x-0,4x=2,8-5,2

             0,2x=-2,4

                  x=-12

4. Пусть х л воды было в каждой цистерне первоначально, тогда

(х-54) л воды стало в первой цистерне, а 

(х-6) л воды стало во второй цистерне.

Т.К. в первой стало в 4 раза меньше, чем во второй, то составим уравнение: 4(х-54)=х-6,  4х-216-х+6+0;  3х=210;  х=70

ответ: в цистернах было по 70л воды

5. (3x+42)(4.8-0.6x)=0

3x+42=0         4.8-0.6x=0

3x=-42             -0.6x=4.8

x=-14                 x=-8
