Answer: SECOND OPTION
Step-by-step explanation:
You can solve the system of equations by the method of substitution:
- You must susbtitute the second equation into the first equation and solve or x:
[tex]7x+2(x+1)=4\\7x+2x+2=4\\9x=4-2\\9x=2\\x=\frac{2}{9}[/tex]
- Now, you must susbtitute the value of x obtained above into the second equation to calculate the value of y. Then, you have:
[tex]y=\frac{2}{9}+1\\\\y=\frac{2+9}{9}\\\\y=\frac{11}{9}[/tex]
Therefore, you obtain:
([tex]\frac{2}{9},\frac{11}{9}[/tex])
