When simplifying algebraic expressions, we should first factorise each term fully to find any common factors. First we should factorise the numerator where 3x²-8x-3 factorises to (3x+1)(x-3). N...

x = -4.8x = -3

First start with 2xy=-4, rearrange to find in terms of x, x=-2/y. Substitute this into the other equation (3x-5=-4y), producing -6/y -5 =-4y.Times every term by -y resulting in 6+5y=4y² .Rearr...
