Given data:

The first equation is y=4x.

The second equation is 8x+y=18.

Substitute first equation into second equation.

[tex]\begin{gathered} 8x+4x=18 \\ 12x=18 \\ x=\frac{3}{2} \end{gathered}[/tex]

Substitute 3/2 for x in the first equation.

[tex]\begin{gathered} y=4(\frac{3}{2}) \\ =6 \end{gathered}[/tex]

Thus, the value of x is 3/2, and the value of y is 6.
