4. Solve the following system of equations for x and y. Find the product y 2x 3y 14 3x 2y ANSWER:Explanation / Answer
2x +3y = 5
3x -2y =14
Solve by eleimnation of variables:
multiply equation 1 by 3 and equation 2 by 2 :
6x +9y = 15
6x -4y = 28
-------------------- (subtract)
13y = -13
y = -1
solve for x: 2x = 5-3y
2x = 5 - 3(-1)
x = 4
Product x*y = -1*4 = -4
