    Answer:4

    Step-by-step explanation:

    let them number be y

    y^2=y+12

    y^2-y-12=0

    y^2+3y-4y-12=0

    y(y+3)-4(y+3)=0

    (y+3)(y-4)=0

    y+3=0 y-4=0

    y=-3 y=4

    There number is 4

    Answer:

    Since the largest number is 12 more than it, the larger number is x+12. Their sum is x+(x+12)=2x+12. 2x+12=48, since their sum is 48, so 2x=48-12=36, and x=36/2=18. Since x is 18, x+12=30, which are the value of the 2 numbers.
