Sqrt(1-3x)=x+3
[sqrt(1-3x)]^2=(x+3)^2
1-3x=(x+3)(x+3)
1-3x=x^2+6x+9
-3x=x^2+6x+8
0=x^2+9x+8
The answers are -1 and -8 BUT, we have to plug them back into the original equation to make sure we don't get a negative under the square root sign.
After doing this, we realize that only -1 works, so the answer is x=-1
Sorry that this took forever to answer. I was thinking of a good way to explain this, and if you need any further explanation, message me:)
Best wishes:)
Answer:
2(a - 4) + 5(b + 1) = 8. The result of this equation when solving is a = - 5b/2 + 11/2.
3(a - 1) - 2(b - 2) = -11. The result of this equation when solving is a = 2b/3 - 4.

It is difficult to overthrow a presidential veto because each house has to have a two-thirds majority vote to overthrow The veto. it is difficult because 2/3 is more than 1/2 and it has to be in each house so it is very difficult. I think this is a good thing because if Congress wanted to pass a bill the president did not like then it is hard for them to pass it and the president is the leader so he should make the big decisions.
