[tex]7x + 2(x + 1) = 4 \\ 7x + 2x + 2 = 4 \\ 9x + 2 = 4 \\ 9x = 2 \\ x = \frac{2}{9} \\ \\ y = \frac{2}{9} + 1 = \frac{11}{9} \\ ( \frac{2}{9} \: \frac{11}{9} )[/tex]
It’s B.

y=x+1

7x+2(x+1)=4

y=x+1
9x+2=4

Subtract 4-2 from the second equation.

The we have y=x+1

9x=2

x=2/9

Then plug in x into the other equation bc now we know it!

y=2/9+1

Which is 11/9

I hope this helps!!!
