Question:
Solve each of the following systems by substitution.
8x - 4y = 16
y = 2x - 4
Answer:
Given equations are,
8x - 4y = 16
y = 2x - 4
substitute the value y = 2x-4 in the first equation...
8x - 4(2x - 4) = 16
==> 8x - 4*2x - 4*4 = 16
==> 8x - 8x - 16 = 16
==> -16 = 16, which is not a true statement...
So the given system equation has no solution..
Hope you found the explanation useful.
Regards.
