# 1


6x-7=17 Start with the given equation.


6x=17%2B7 Add 7 to both sides.


6x=24 Combine like terms on the right side.


x=%2824%29%2F%286%29 Divide both sides by 6 to isolate x.


x=4 Reduce.


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

Answer:

So the answer is x=4




# 2


10-3%28x%2B2%29=31 Start with the given equation.


10-3x-6=31 Distribute.


-3x%2B4=31 Combine like terms on the left side.


-3x=31-4 Subtract 4 from both sides.


-3x=27 Combine like terms on the right side.


x=%2827%29%2F%28-3%29 Divide both sides by -3 to isolate x.


x=-9 Reduce.


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

Answer:

So the answer is x=-9
