1. Consider the system of equations
5x + y = 31
-3x + 4y = -37
Solve the first equation for y in terms of x

Enter your answer in the form y =

2. following after question 1

Take your expression for y from part (a), and substitute it into the second equation. Solve for x and y.
Enter your answer as the ordered pair (x,y).

3. Solve for x in terms of y if 4x + 2y = 7

4. Find the ordered pair (x,y) that satisfies the system of equations

2x + y &=-7
x =4+2y.
