Answer:
[tex]x=-\frac{21}{4}[/tex]
Step-by-step explanation:
[tex]Given\ y=-x-2\ and\ y=\frac{1}{4}+3\\\\y=\frac{1}{4}+3\\\\y=\frac{1+3\times 4}{4}\\\\y=\frac{13}{4}\\\\Substitute\ the\ value\ of\ y\ in\ y=-x-2\\\\y=-x-2\\\\x+y=-2\\\\x=-y-2\\\\x=-\frac{13}{4}-2\\\\x=-\frac{13+8}{4}\\\\x=-\frac{21}{4}[/tex]
