Answer:


x=2(2)/(17)

Explanation:

Do the distributive property.
-3x+14+20x+72=122

Reorder the equation to make it easier to combine common terms.
-3x+20x+14+72=122

Combine common terms.
17x+86=122

Subtract 86 from both sides of the equation to isolate the 17x.
17x=36

Divide both sides of the equation by 17 to isolate the x.
x
2.118 or
x=2(2)/(17)
