Answer:
3x-x+2=4
Step-by-step explanation:
Children = x
Adults = y
x + y = 754...1
1.50x + 2.25y = 1422...2
Multiply (1) by 2.25
2.25x + 2.25y = 1696.50...3
1.50x + 2.25y = 1422...2
Subtract (2) from (3)
0.75x = 274.50
x = 366
Substitute x = 366 in (1)
x + y = 754
366 + y = 754
y = 388
366 children and 388 adults swam at the pool.
Okay so you do 6r-8r which = -2r
Then you do 5t-4t which = 1t
So the answer simplified = -2r + 1t
It can be factored.
We need two numbers that multiply to -12 and add to -4, so are two terms would be -6 and 2.
(x - 6) (x + 2) = 0
x = 6
x = -2
