I need help! I don't understand how to get x and y. I need them in order to complete the question.

a+b=180

13y+31y+4=180

44y=176

y=4

r=s

130x-160=30x+40

x=2

b=128

a=52

s=100

r=100

hopefully its correct (✿^‿^)

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.

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
