Let x = price of a pizza y= price of a salad 2x +y=29.00 3x+2y=46.00 Solve the system of equations in problem #5. -4x-2y =-58.00 (Multiply the first equaton by -2.) 3x +2y =46.00 ---------------------------------- -x =-12 x=12.00 price of a pizza. From this equation: 2x+y=29.00 2(12)+ y=29.00 24+y=29.00 y=29=24 y=5 What is the cost of one salad? $4 $5 $6 $7 ANSWER: Cost of a salad is $5.
