Question

X = 19 - 3y 2y + 3x = 22

Answer 1

Let:

`\begin{gathered} x=19-3y_{\text{ }}(1) \\ 2y+3x=22_{\text{ }}(2) \\ \end{gathered}`

Replace (1) into (2):

`\begin{gathered} 2y+3(19-3y)=22 \\ 2y+57-9y=22 \\ -7y=-35 \\ y=(-35)/(-7) \\ y=5 \end{gathered}`

Replace the value of y into (1):

`\begin{gathered} x=19-3(5) \\ x=19-15 \\ x=4 \end{gathered}`
