maths 0.0 / 5 ? AllmathsGCSEAQA Created by: LIberty BaileyCreated on: 17-03-15 17:26 solve, x/3-1=x-5/2? Lcm (2,3)=6 . 6x/3-6= 6(x-5)/2 . x=9 1 of 5 solve, x+2/5+x-4/3= x/2? lcm (5,3,2)= 30 , 30(x+2)/5 + 30(x-4)/3 = 30x/2. then divide '30 by bottom number' final answer x=28 2 of 5 For simultaneous what does ++ mean and +- ++= - (SAME) -+= +(Different ) 3 of 5 Simultaneous equations steps? label 1 and 2. decide to - or +. the y signs cancel and you can carry on with your sums. then subs in 4 of 5 try , 3x+y=13 and 2x+y=9? x=4 y=1 5 of 5
