The sum of two numbers is 105. If the larger number is increased by twice the smaller number, the result is 138. What is the larger number? If x is the smaller number and y is the larger number, which of the following system of equations represents the word problem?

x+y=105

x+2y=138

x-y=105

y+2x=138

x+y=105

y+2x=138

    The last set of equations is correct:

    x + y = 105

    y + 2x = 138

    Subtract the top equation from the bottom equation to cancel out y:

    2x - x = 138 - 105

    x = 33

    Plug value of x into top equation:

    33 + y = 105

    y = 105 - 33

    y = 72

    So the larger number is 72.
