Answer:

The variable that needs to be eliminated in these systems of equations are 3x

Step-by-step explanation:

-3x + 4y = -50

3x + 3y = -6

*solve from top to bottom, if that makes sense, so add 3x to -3x, 4y to 3y, and -50 to -6.*

0 + 7y = -56

7y = -56

*divide by 7 to get y alone*

y = -8

plug y into one of the original equations to get x

-3x + 4y = -50

-3x + 4(-8) = -50

-3x - 32 = -50

     +32    +32

-3x = -18

x = 6

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 ;)
