So we want to find x and y so that:
For this, we have to remember that both matrices have equal components.
So we could equal:
[tex]\begin{gathered} x+3=4 \\ y=2x+2 \end{gathered}[/tex]
We could solve the first equation:
[tex]\begin{gathered} x+3=4 \\ x=4-3 \\ x=1 \end{gathered}[/tex]
And, as we know that x=1, we could replace this value in the expression:
[tex]\begin{gathered} y=2x+2 \\ y=2\cdot1+2 \\ y=2+2 \\ y=4 \end{gathered}[/tex]
And these are the values for x and y.
