1)
4x +5 = 19 +2x

4x - 2x = 19 - 5

2x = 14

x =  \frac{14}{2}

x = 7

---------------------------------------------------------------------------------------

2)

3(x+2) - 2× (x+6) = 4 ( x -3)

3x + 6 - 2x -12 = 4 x - 12

3 x - 2 x + 6 -12 = 4 x - 12

x - 6 = 4 x -12

x - 4x = -12 +6

-3x = -6

x =  \frac{-6}{-3}

x = 2

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

3)

 \frac{x}{4} - 8x = 0

 \frac{x}{4}  -  \frac{8x}{1}  = 0

 \frac{x - 32 x}{4}  = 0

 \frac{-31 x }{4}  = 0

-31 x = 0 × 4

-31 x = 0

x =  \frac{0 }{-31}

x = 0

---------------------------------------------------------------------------------------------------------------------------------------------------------------

4)

 \frac{x -3 }{5}  - 2 = - 4

 \frac{x -3 }{5}   -  \frac{2}{1}  = -4

 \frac{x-3 -10}{5}  = -4

 \frac{x-13}{5}  = -4

x - 13 = - 4× 5

x - 13 = -20

x = -20 + 13

x = -7

----------------------------------------------------------------------------------------------------------------------------------------------------------------

5)

7 (x+5) = 49

7x + 35 = 49

7x = 49 - 35

7 x = 14

x =  \frac{14}{7}

x = 2
