i took algebra a couple years ago :)
Answer:
4+ 
x = 3
Step-by-step explanation:
4 + x = 3 (subtract 4 from both sides)
x = -1 (multiply both sides by 2)
x = -2
7:9 because there are 35 children and 10 adults. Add 35 and 10 you get 35:45 then you simplify the ratio to get 7:9.
The slope of the first equation would be -5/2 because
2y=-5x+8
y=-5x/2+4
The y intercept of the 2nd equation is when x=0, so -7y=10
y=-10/7
The equation of the line would be y=-5x/2-10/7
Or in standard form....
5x/2+y=-10/7
5x+27=-20/7
Good luck I have no freaking
clue
