Answer:
Question 1: (1,5) (I believe that is the format they are looking for.)
Question 2: (5,7)
Step-by-step explanation:
Just substitute the letters for the numbers they give you then solve.
Question 1:
y = 5
5 = x + 4 Subtract 4 from both sides.
1 = x
Question 2:
x = 5
y = 2 · 5 - 3
y = 10 - 3
y = 7
