Question

resolver siguientes ecuaciones
1). 8x+5-3+8x=25-3x+20
4). 8x+4-3x=-3x+19
3). 4+5x-2+8=-15x-3+19​

Answer 1

Explicación paso a paso:

1) 8x+5-3+8x = 25-3x+20

8x+8x+3x- = 25+20-5+3

16x + 3x = 45-5+3

19x = 41 + 3

19x = 44

x = 44/19

4) 8x+4-3x = -3x+19

8x-3x+3x = 19-4

5x+3x = 15

8x = 15

x = 15/8

3) 4+5x-2+8 = -15x-3+19

5x+15x = -3+19-4+2-8

20x = 16-4 = 12+2 = 14-8 = 6

x = 6/20

x = 3/10
