x+5x-4=18-2x
3x-2+7x=7-1
10x-2x-6=6x-4x+24
4(x-6)=12-(x+3)
3(x+6)-(3x-4)=8-4(3-x)

Answer 1

Explicación paso a paso:

1) X + 5x - 4 = 18 - 2x

6x - 4 = 18 - 2x

6x + 2x = 18 + 4

8x = 22

X = 11/4

2) 3x - 2 + 7x = 7 - 1

10x - 2 = 6

10x = 8

X = 4/5

3) 10x - 2x - 6 = 6x - 4x + 24

8x - 6 = 2x + 24

6x = 30

X = 5

4) 4(x - 6) = 12 - (x+3)

4x - 24 = 12 - x - 3

4x + x = 9 + 24

5x = 33

X = 33/5

5) 3(x + 6) - (3x - 4) = 8 - 4(3 - x)

3x + 18 - 3x + 4 = 8 - 12 + 4x

22 = 4x - 4

26 = 4x

13/2 = x
