1-x-7/3=x+9/4-3x-8/12
lisabon 2012 [21]

Answer:

x = 2 11/12

Step-by-step explanation:

Multiply the equation by 12. This eliminates fractions.

... 12 -12x -28 = 12x +27 -36x -8

Collect terms.

... -16 -12x = -24x +19

Add 24x+16

... 12x = 35

Divide by the coefficient of x

... x = 35/12 = 2 11/12
