Answer:
y = -1x -3
Step-by-step explanation:
Answer:
q = - 14 / 17
Step-by-step explanation:
9 - 17q = 23
-17q = 23 - 9
-17 q = 14
q = - 14 / 17
700 (seven hundred), 43,000,000 (forty-three million), 554 (five hundred and fifty-four)

0.35x + 0.60y = 0.40(x + y) where x = vol. of 35% and y = vol. of 60%
x + y = 20
solve this system of equations
x + y = 20
-0.05x +0.20y = 0
this gives x = 16 and y = 4
so you need 16 L of 35% and 4 L of 60% solution.
