Answer:
c) both (1,2) and (2,4)
Step-by-step explanation:
You solve this by plugging the numbers in and seeing if they are equal to each other.

3x+3y= -x+5y
4x=2y
2x=y
y=2x
Means that the y value is 2 times the x value.
answer: C but there are more solutions than just (1,2) and (2,4)

You have 3c (3 times her cousins age) -4 (4 less than)
4y=-5x+15
y=-5/4x+15/4
y-1/2=4/5(x-1/2)
y-1/2=4/5x-2/5
y-5/10=4/5x-4/10
y=4/5x+1/10
