Question

Solve for X. 5-3x= 12x + 4 X= 1/?

Answer 1

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

Answer 2

5-3x=12x+4

5=15x+4

15x=1

x=1/15
