Let
R = Ralph's age
S = Sara's age
First statement is translated as:
S = 3R
Second statement is translated as:
S + 4 = 2(R + 4)
Use the first equation to be substituted into the second one in terms of R which is the one we are actually going to solve for Ralph's age.
Since S = 3R, then
3R + 4 = 2(R + 4)
3R + 4 = 2R + 8
3R - 2R = 8 - 4
R = 4 years old

Step-by-step explanation:
Answer:
b.y=4
c. x=6
These are the answers hope this helps
I would say the answer is 8.25
The first one is D. Y=-3+8x
The second one is G. -3/2x=y+2
