The first equation is

y = 6x - b

For the system to have an infinite number of solutions, both equations must be the same equation.

Solve the second equation for y.

-3x + 1/2 y = -3

1/2 y = 3x - 3

y = 6x - 6

Compare this with the first equation,

y = 6x - b

That means b = 6

Lets begin with our y=mx+b, our constant(b) is 800 that she earns as a salary, our x represents the amount she sells, m then represents the commission which is 8.25% so converting that to a decimal and replacing it as m gets us y = 0.0825x+800. Replace $4500 for x and we have y=0.0825(4500)+800 solve and we get $1171.25
