Relative values of y in terms of x: 5x - 4y = one million 4y = 5x - one million y = (5x - one million)/4 - 10x + 8y = - 3 8y = 10x - 3 y = (10x - 3)/8 value of x: 8(5x - one million) = 4(10x - 3) 2(5x - one million) = 10x - 3 10x - 2 = 10x - 3 3 = 2 is fake answer: there is a few thing incorrect someplace in a single or the two between the equations. Ergo, there is answer to this subject.

5x - 4y = 1
10x + 8y = -3
Multiply top by -2
-10x + 8y = -2
10x + 8y = -3
16y = -5
y = (-5/16)
5x - 4(-5/16) = 1
5x + (20/16) = 1
5x + (5/4) = 1
20x + 5 = 4
20x = -1
x = (-1/20)
x = (-1/20)
y = (-5/16)

stmc is almost corrent except there is no solution, since 0 cannot be equal to -1.
