Given
find the value of y when x = -10
2x - 9y = -38
Solution
We are going to plug x = -10 into the equation
[tex]\begin{gathered} 2(-10)-9y=-38 \\ -20-9y=-38 \end{gathered}[/tex]collect the like terms
[tex]\begin{gathered} -9y=-38+20 \\ -9y=-18 \end{gathered}[/tex]Divide both sides by -9
[tex]\begin{gathered} -\frac{9y}{-9}=-\frac{18}{-9} \\ \\ y=2 \\ \end{gathered}[/tex]The value of y is 2
