Ответ:
The value of a and b from the given equation is 2 and -1 respectively;
Given the equation![7(ay^2+by-3)=14y^2-7y-21](/tpl/images/0023/4150/cb18b.png)
In order to get the value of a and b that will make the equality equation true, we will have to factorize first;
Next is to compare both sides to get the unknown value
Get the value of "b"
Hence the value of a and b from the given equation is 2 and -1 respectively;

Ответ:
a = 2 and b = - 1
Step-by-step explanation:
distribute the left side of the equation and compare the like terms with terms on the right side
7ay² + 7by - 21
compare the coefficients of like terms with 14y² - 7y - 21
7a = 14 ⇒ a = 2
7b = - 7 ⇒ b = - 1
