Question

Solve the following system of equations for x and y2x + 2y = 92x - y = 3

Answer 1

2x + 2y = 9

2x - y = 3

Method Elimination

2x + 2y = 9 -------------- Eq 1

4x - 2y = 6 --------------- Eq 2

6x = 15

x = 15/6

x = 5/2

Find y

2(5/2) - y = 3

5 -y = 3

5 - 3 = y

y = 2

Result

x = 5/2, y = 2
