Answer:
x=-22/4
y=-3
Step-by-step explanation:
3x-2y=-5
4x+2y=-16
we <u>add</u> the equation
7y=-21
y=-3
then we find the x by taking a random equation
I take 4x+2y=-16
4x+2(-3)=-16
4x-6=-16
4x=-22
x=-22/4
For downstairs- 28 x 38= 1064
For upstairs- 26 x 14= 364
All together- 1064 + 364= 1428
So.... 1428 seats in total.
Hope this helped! :)
15x-20<130
15x<130+20
15x<150
X=150/15
x<10
