Primer sistema
2x + y = 14
x = y + 1
y = 14 - 2x
x = 14 -2x +1
x + 2x = 15
3x = 15
x = 5
x = y + 1
5 = y + 1
y = 4
Segundo sistema
2x + 2y = 160
x = 3y
2(3y) + 2y = 160
6y + 2y = 160
8y = 160
y = 20
x = 3y
x = 3(20)
x = 60
Tercer sistema
2x - y = 15
x = 2y
2(2y) - y = 15
4y - y = 15
3y = 15
y = 5
x = 2y
x = 2(5)
x = 10
