Question

помогите решить
1)15x + 10 = 6x – 8
2) 14x − 25 = 20x + 9
3) -3(5 - x ) = 35 - 5x
4) 10x − 8 = 20x + 74
5) 13x + 8 = 27x + 18

Answer 1

1) 15x + 10 = 6x – 8

15x-6x=-8-10

9x=-18

x=-2

2) 14x − 25 = 20x + 9

-25-9=20x-14x

6x=-34

x= - 34/6 = - 17/3

x=-5 2/3

3) -3(5 - x ) = 35 - 5x

-15+3x = 35-5x

3x+5x=35+15

8x=50

x=50/8=25/4

x=6 1/4=6.25

4) 10x − 8 = 20x + 74

20x-10x=-8-74

10x=-82

x=-82/10 = -41/5

x=-8.2

5) 13x + 8 = 27x + 18

27x-13x=8-18

14x=-10

x=-10/14

x=-5/7
