Ok let me explain it to you like this: Let the price for one egg be x and the price for one toast be y Then: <span><span>3 = </span><span><span>2x+1y, </span><span>1.8 = 1x+1y.</span></span></span><span>When we substract, we get x = 1.2 and y = 0.6, so the price for an egg is $1.20 and the price for a toast is $0.60. </span>Hope this is helpful
