Answer: (4, 19
Given:
[tex]\begin{gathered} y=4x+3 \\ y=7+3x \end{gathered}[/tex]
Substitute the second equation to the first to solve for x:
[tex]\begin{gathered} y=4x+3 \\ 7+3x=4x+3 \\ 3x-4x=3-7 \\ -x=-4 \\ x=4 \end{gathered}[/tex]
Then, we will substitute the value of x to the first equation to solve for y:
[tex]\begin{gathered} y=4x+3 \\ y=4(4)+3 \\ y=16+3 \\ y=19 \end{gathered}[/tex]
The solution would then be (4, 19)
