Question

Nếu \(5\left(2x-1\right)+8x=13\). Khi đó \(x=?\)

Answer 1

5(2x-1) + 8x = 13 

10x - 5 + 8x = 13

18x - 5         = 13

18x               = 13 + 5

18x              = 18

x                   = 1 

Answer 2

=> 10x - 5 + 8x = 13

=> 10x + 8x = 13 + 5

18x = 18

x = 18 : 18 

x = 1      

Answer 3

5(2x-1)+8x=13

10x-5+8x=13

10x+8x-5=13

18x=13+5

18x=18

x=18:18

x=1
