Question

Find the value of y when x = -102x - 9y = -38

Answer 1

Given

find the value of y when x = -10

2x - 9y = -38

Solution

We are going to plug x = -10 into the equation

`\begin{gathered} 2(-10)-9y=-38 \\ -20-9y=-38 \end{gathered}`

collect the like terms

`\begin{gathered} -9y=-38+20 \\ -9y=-18 \end{gathered}`

Divide both sides by -9

`\begin{gathered} -(9y)/(-9)=-(18)/(-9) \\ \\ y=2 \\ \end{gathered}`

The value of y is 2
