I'm telling you add "10x^3/y" at the start, "y/(5x)^2" in the middle and "5/2x" at the end of every equation (ensure all are on the same side of the '=' sign and only separated by the multiplication function).
Did you factor in Blue sunlight, white sunlight, sun dipping, wind pressure, time of day, time of year, age, testosterone level (don't lift right after happy time), who is writing him, diet, dumbbell vs barbell, supplements taken before working out, time between doing that excerise, warmup conditions, previous injuries, additional algebraic/physics equations that actually cancel each other out but make you look brilliant in front of the unsuspecting, etc... ???
