Solve for X.

5-3x = 12x + 4

X = 1/?

5-3x=12x+4

5=15x+4

15x=1

x=1/15

Solve for x:

5 - 3 x = 12 x + 4

Subtract 12 x from both sides:

5 + (-3 x - 12 x) = (12 x - 12 x) + 4

-3 x - 12 x = - 15 x:

-15 x + 5 = (12 x - 12 x) + 4

12 x - 12 x = 0:

5 - 15 x = 4

Subtract 5 from both sides:

(5 - 5) - 15 x = 4 - 5

5 - 5 = 0:

-15 x = 4 - 5

4 - 5 = - 1:

-15 x = - 1

Divide both sides of - 15 x = - 1 by - 15:

(-15 x) / (-15) = (-1) / (-15)

(-15) / (-15) = 1:

x = (-1) / (-15)

Multiply numerator and denominator of (-1) / (-15) by - 1:

Answer: x = 1/15
