Q= -1. I did this problem by elimination, by multiplying the first one by -4 and the second by 3, to cancel out the p. I ended up with -7q=7. I divided both sides by -7, and got q=-1.

(x-1)(x+2)=5(x-1) divided by x-1
anyanavicka [17]
Assuming that your question is (x-1)(x+2) = [5(x-1)]/x-1

On the right side, the x-1's will cancel out, leaving you with (x-1)(x+2) = 5

expand the left side, giving you x^2 + x -2 = 5
which goes to x^2 +x -7 = 0
the possible values for x are 2.93 and -3.93. I don't think this was your question, so I'll do the other possible question that you might have been asking.

(x-1)(x+2) = 5(x-1)

divide by x-1 on both sides, leaving you with x+2=5
x+2=5
x=5-3
x=3

Trina invited 60 people to her party and 42 said they would attend. What percent of people said they were NOT able to attend? Pl
Llana [10]
1. simplify 42/60 to 7/10 (42/60 divided by 2 is 21/30, 21/30 divided by 3 is 7/10)
2. if 10 x 10 = 100 than 7 x 10 = 70 so that would make it 70/100 which is 70%
so 70% is the answer

Hope this helps ;)
