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.

Question

x = 0.7(300 - y)

y = 0.8(300 - x)

What is the x value
what is the y value

Answer 1

x+.7y=210
.8x+ y=240

then solve by any method. I would multiply the first equation by .8, then subtract the second equation
