thank you

Answer 4

y - 2x = 8 --- we want to get y by itself, therefore, we want the -2x on the other side.
To do this, we do the opposite. It is showing -2x, so we add 2x to both sides.
y - 2x + 2x = 2x + 8 -- combine like terms
y = 2x + 8
now that we have y = 2x + 8, we can sub 2x + 8 in for y in the other equation.
16 + 4x = 2y
16 + 4x = 2(2x + 8) -- distribute through the parenthesis
16 + 4x = 4x + 16 -- subtract 4x from both sides
16 + 4x - 4x = 4x - 4x + 16 -- combine like terms
16 = 16
if the solution ends like this, there are INFINITE SOLUTIONS

if it would have ended like this : 16 = 14...then it would be no solutions.
