Talk:Leaving Certificate Mathematics/Algebra

Hi folks, is it only proposed to include the Exam questions, what about suggested solutions?

Take for example 2003 2(a) a posible suggested solution could look like below: Suggested solution: (i)The first equation is linear, the second not,so find y in linear equation: 3x-y=8, -y=-3x+8, y=-3x-8, (ii)substitute value of y in second equation and solve for x: x^2 + (3x-8)^2 = 10 x^2+9x^2-48x+64=10 10x^2-48x+54=0 (5x-9)(2x-6)=0 5x-9=0 or 2x-6=0 x=9/5 or x=3 (iii) substitute values of x in linear equation for y: x=9/5: y=3(9/5)-8, y= 27/5-40/5=-13/5 x=3: y=3(3)-8, y=9-8=1
