y = 0.8(300 - x)
y = 240 - .8x
x = 0.7(300 - y)
x = 210 - .7y
sub y = 240 - .8x into
x = 210 - .7y
x = 210 - .7(240 - .8x)
x = 210 - 168 + .56x
.44x = 42
x = 42/.44 = 4200/44 = 1050/11
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?
