Berto has $12 to put gas in his car. if gas cost $3.75 per gallon, which ordered pair relating number of gallons of gas, x,to the total cost of gas, y, includes the greatest amount of gas Berto can buy?

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
