Solve by the elimination method 2x 5y 29 5x 6y 20Solutio

Solve by the elimination method 2x - 5y = 29 5x + 6y = -20

2x -5y = 29 ----(1)

5x + 6y = -20 ----(2)

Multiply equation 1 by 5 and equation 2 by2 to eliminate x:

10x - 25y = 145

10x +12y = -40

-------------(subtract)

-37y = 185

y = -185/37 = -5

y = -5

2x -5y = 29 ----> 2x = 29 +5*5

2x = 54

x = 27

Solution : ( x , y) = (27 , -5)
