Answer 1

Explicación paso a paso:

1) 8x+10 = 4x-6

8x-4x = -10-6

4x = 16

x = 16÷4

x = 4

2) -12+9x = 2x+2

9x-2x = 12+2

7x = 14

x = 14÷7

x = 2

3). 15x-9 = 3x+3

15x-3x = 9+3

12x = 12

x = 12÷12

x = 1

4). 18+14x = 4x-16

14x-4x = -18-16

10x = 2

x = 10÷2

x = 5

5). 9x-7 = 5x+21

9x-5x = 7+21

4x = 28

x = 28÷4

x = 7

Answer 2

8x + 10 = 4x - 6
8x + 10 - 4x = 4x - 6 - 4x
8x - 4x = -6 - 10x
4x = -16
4x ÷ 4 = -16 ÷ 4
X= -4

-12 + 9x = 2x + 2
9x - 2x = 2 + 12
7x = 14
7x ÷ 7 = 14 ÷7
7x = 14
X= 2

15x - 9 = 3x + 3
15 - 3x = 3 + 9
12x = 12
12x ÷ 12 = 12 ÷ 12
X= 1

18 + 14x = 4x - 16
18 + 14x - 4x = -16
14x -4x = -16 - 18
10x = -34
10x ÷10= -34 ÷ 10
X= -34/10 simplificar
X= -17/5 = -3,4


9x -7 = 5x + 21
9x -5x = 21 + 7
4x = 28
4x ÷ 4 = 28 ÷ 4
X = 7
