The difference of two numbers is 9 and the sum of the numbers is 55. what are the numbers ?

Difference is 9: x-y=9

From the second equation x=9+y (substitute that into the first equation to solve for y).

9+y+y=55

so, 2y= 55-9

2y=46

y= 46/2

y=23. (Substitute that back into the second equation to find x.)

x=9+y = 23+9 = 32.

23+32 = 55 (Check).

Hope the solution helped.

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
