What values of x and y satisfy - 133x-2y=7 and 3x+25y=5 simultaneously?

1) - 133x - 2y = 7

2) 3x + 25 y = 5

Multiply 1) by 25 and 2) by 2, then

1a) - 3325x - 50y = 175

2a) 6x + 50y = 10

Add the 1a) and 2a)

3) - 3319x = 185

x = - 185 / 3319 = - 0.056

from 1) y = (-133 (x) - 7) / (2) = [-133 (-185/3319) - 7]/2 = 0.207
