Solve the following system of equations. You will type your x value in the first part and the y value in the second part of the question. If the answer if no solution then type NS in both parts and if the the answer is infinite solutions then type I in both parts.
x = 0.7(300 - y)
y = 0.8(300 - x)
What is the x value
what is the y value
x+.7y=210
.8x+ y=240
then solve by any method. I would multiply the first equation by .8, then subtract the second equation
