Callie ng88 SG Please help to solve this equation with workings:square root of -2x + square root of y = 5square root of -2x - square root of y = -13x + y = 3Thanks.
tinuviel07 SG Please help to solve this equation with workings:square root of -2x + square root of y = 5square root of -2x - square root of y = -13x + y = 3Thanks.y =12?
dkcx SG When did simulataneous equations start requiring 3 equations? Can't it be done but just changing the 3rd equation to y = 3-3x and sub it into either of the above 2 equations?Having square root of -2x means x has to be a negative value liao since u don't square root negative numbers.
skythewood SG Bring "square root of -2x" to one side. bring the other stuff to the other side.Square both side. get equation. do this first.
crimson soldier SG this isn't too hard, I encourage you to solve it yourself. Answer: y=9, x= -2 I too am wondering why you have 3 equations for 2 variables
