Question

2x + 3y=2 -6x + 12y = 1​

Answer 1

Respuesta:

2x + 3y = 2 = x = 2 - 3y / 2

-6x + 12y = 1 = x = 1 - 12y / 6

2-3y / 2 = 1-12y / 6

2-3y / 6 = 1-12y / 6

3•(2-3y) / 6 = 1-12y / 6

3• (2-3y) = 1-12y

6 - 9y = 1 - 12y

-9y +12y = 1 - 6

3y = -5

3y / 3 = -5 / 3

y = -1

2-3•(-1) / 2

2 + 3 / 2

5 / 2

x = 2
