Answer 1

\(\left(5x-2\right)-64=-36\\ =>\left(5x-2\right)=-36+64\\ =>5x-2=28\\ =>5x=28+2\\ =>5x=30\\ =>x=30:5\\ =>x=6\)

Answer 2

Answer 3

(5.x - 2) - 64 = - 36

 5.x - 2         = (- 36) + 64

 5.x - 2         = 28

 5.x              = 28 + 2

 5.x              = 30

    x              = 30 : 5

    x              = 6

 Vậy x          = 6

Answer 4

\(\left(5.x-2\right)-64=-36\)

\(\left(5.x-2\right)=-36+64\)

\(5.x-2=28\)

\(5.x=28+2\)

\(5.x=30\)

\(x=30:5\)

\(x=6\)
