Question

Complete the solution of the equation. find the value of y when x equals 1. 9x +7y= -12​

Answer 1

Answer:

$y=-3$

Step-by-step explanation:

Given Equation:  

                            $9x +7y=-12$             y=?       at    x= 1

Putting the given value of 'x' in the equation:

                            $9(1) +7y=-12\\\\9+7y=-12\\\\7y=-12-9\\\\7y=-21\\\\y=-\frac{21}{7} \\y=-3$

At $x=1$, the value of y is $y=-3$
