-1/2x = -1/4y - 21
-x = -1/2y - 42
where did the -1/2y and 42 come from?
-x = -1/2y - 42
where did the -1/2y and 42 come from?
-
(1/2) is brought to the right side of the equation by multiplying both sides of the equation by 2.
(2)(-1/2)x = (2)(-1/4)y - (2)(21)
-1x = -1/2y - 42
(-1/4) * 2 = (-1/2) and 21 * (2) =42.
Hope this helps!
