# 1


5a%2B4%283a-8%29=4%2B13a Start with the given equation.


5a%2B12a-32=4%2B13a Distribute.


17a-32=4%2B13a Combine like terms on the left side.


17a=4%2B13a%2B32 Add 32 to both sides.


17a-13a=4%2B32 Subtract 13a from both sides.


4a=4%2B32 Combine like terms on the left side.


4a=36 Combine like terms on the right side.


a=%2836%29%2F%284%29 Divide both sides by 4 to isolate a.


a=9 Reduce.

Answer:

So the answer is a=9

-x-%2813%2B4x%29=-3%285-9x%29%2B2 Start with the given equation.


-x-13-4x=-15%2B27x%2B2 Distribute.


-5x-13=-15%2B27x%2B2 Combine like terms on the left side.


-5x-13=27x-13 Combine like terms on the right side.


-5x=27x-13%2B13 Add 13 to both sides.


-5x-27x=-13%2B13 Subtract 27x from both sides.


-32x=-13%2B13 Combine like terms on the left side.


-32x=0 Combine like terms on the right side.


x=%280%29%2F%28-32%29 Divide both sides by -32 to isolate x.


x=0 Reduce.


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

Answer:

So the answer is x=0
