You must perform indicated multiplication...

2x(x)+2x(1)+1(x)+1(1)

2x^2+2x+x+1 now combine like terms...

2x^2+3x+1

Answer:

x = 8, y = 2

Step-by-step explanation:

Multiply the second equation by -2:

x + 6y = 20

-2x - 6y = -28

Add the equations and simplify:

-x = -8

x = 8

Plug x = 8 back into the first equation and solve for y:

8 + 6y = 20

6y = 12

y = 2
