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.
