5x-4=2(3x+2)

5x-4=6x+4

5x-6x=4+4

-x=8

x=-8

checking the solution

(5×-8)-4=2((3×-8)+2)

-40-4=2(-24+2)

-44=2(-22)

______________________________________

______________________________________

 \tt\bold{5x - 4 = 2(3x + 2)}  \\

  \tt\bold{5x - 4 = 6x + 4} \\

 \tt\bold{5x - 6x = 4 + 4} \\

  \tt\bold{ - 1x = 8} \\

 \tt\bold{x =  \frac{8}{ - 1} } \\

  \tt\bold{x =  - 8} \\

Verification

 \\

  \tt\bold{5( - 8) - 4 = 2 (3 \times  - 8 + 2)  } \\

\tt\bold{ - 40 - 4 =2( - 24 + 2 }) \\

 \tt\bold{ - 44 =2( - 22) } \\

\tt\bold{ - 44 =  - 44} \\
