Question

x-5=8x+13 4(x-3)=2x-8(x-2) 2x-1=6x

Answer 1

x - 5 = 8x + 13
x - 8x = 13 + 5
- 7x = 18(multiplicando por -1)
7x = - 18
x = - 18/7

4(x- 3) = 2x - 8(x - 2)
4x - 12 = 2x - 8x + 16
4x - 2x + 8x = 16 + 12
10x = 28
x = 28/10 = 14/5

2x - 1 = 6x
2x - 6x = + 1
- 4x = + 1(multiplicando por -1 )
4x = - 1
x = - 1/4
