Question

Gabarito
1) y = -x + 3
2) y = 2x -1.
3) x + y +3 = 0
4) 2x - 3y - 13 = 0
5) 3x - 3y + 6 = 0​

Answer 1

1) y = -x + 3

0 = - x + 3

x= 3

2) y = 2x - 1

0 = 2x - 1

x = 1/2 ou x = 0,5, x = 2^-1

3) x + y +3 = 0

x + y + 3 - 3 = 0 - 3

x + y = - 3

4) 2x - 3y - 13 = 0

2x - 3y - 13 + 13 = 0 + 13

2x - 3y = 13

5) 3x - 3y + 6 = 0

3x - 3y = - 6

x - y = - 2
