Answer:
x = -3
Step-by-step explanation:
x + 3y = -5
x = -3y - 5
2(-3y - 5) - y = 11
-6y - 10 - y = 11
-7y - 10 = 11
-7y = 21
y = -3
Answer:
Step-by-step explanation:
Here, Let the number of weeks = x
Then, Equation would be: 850x - 300x - 7500 = 0
550x = 7500
x = 7500 / 550
x = 13.63
Minimum week can't be in decimal, so we have to pick for nearest larger value which is 14.
In short, Your Answer would be: 14 Weeks
Hope this helps!
