The answer should be less than
Answer:
The reasonable range is 0 ≤ y ≤ 11,110, while the mathematical range is y ≥ –20.25.
Step-by-step explanation:
Answer: " y = 21 " .
____________________________________________
Cross multiply:
______________________________
(2y)(4) = 7(y + 3) ;
8y = 7y + 21
Subtract 7y from each side of the equation;
8y - 7y = 7y + 21 - 7y ;
y = 21 .
