Answer:
The answer is the option B
[tex]x=0[/tex]
Step-by-step explanation:
we have
[tex]-x+2y=6[/tex] -----> equation A
[tex]6y=x+18[/tex] ------> rewrite ----> [tex]x+18=6y[/tex] -----> equation B
Adds equation A and equation B
[tex]-x+2y=6\\x+18=6y\\----------\\2y+18=6+6y\\6y-2y=18-6\\4y=12\\y=3[/tex]
Find the value of x
[tex]-x+2y=6[/tex] ------> substitute the value of y and solve for x
[tex]-x+2(3)=6[/tex]
[tex]x=0[/tex]
