Given:
Equations are y = 3x - 1 and 2x + 6 = y
Required:
Solve this system of equations using the substitution method.
Explanation:
We will proceed as:
[tex]\begin{gathered} y=3x-1....(1) \\ 2x-y=-6.....(2) \end{gathered}[/tex]
Put equation (1) in eq. (2), we will get
[tex]\begin{gathered} 2x-3x+1=-6 \\ -x=-7 \\ x=7 \end{gathered}[/tex]
and y = 3(7) - 1
y = 20
Answer:
Hence, x = 7 and y = 20.
