may someone help me please, I've attempted it three times and no luck! :(
3(-10z-1)+5=6(-5z+1)-9

noelgreco · Answer

Distributive property of multiplication over addition.

-30z-3+5 on the left - evaluate

anonymous · Answer

i get 2=-3

noelgreco · Answer

Well, that can't be right!  You have to collect like terms.  the 30z is one type of term (has a variable), and the - 3 and 5 are alike because they're just numbers.

What is -3 + 5?

anonymous · Answer

2?

noelgreco · Answer

Good.  That's the left side only.  Now, the right side.

Now try distributing on the right and collecting like terms.

anonymous · Answer

is it -3?

noelgreco · Answer

Well, it's actually -30z - 3.

So -30z +2 = -30z -3

Adding 30z to both sides, you get 2=-3.  That's not true, so there is no solution.

What did the original quetion ask.  Solve for x, or what is the solution set?

anonymous · Answer

anonymous · Answer
