Question

Como calcular equaçao 3x/5+2y/15=1/3

Answer 1

3x/5 + 2y/15 = 1/3

3(1)/5 + 2(-2)/15 = 1/3

3/5 - 4/15 = 1/3

9/15 - 4/15 = 1/3

5/15 = 1/3

1/3 = 1/3 É

b) ( - 1, 7)

3x/5 + 2y/15 = 1/3

3(-1)/5 + 2(7)/15 = 1/3

-3/5 + 14/15 = 1/3

-9/15 + 14/15 = 1/3

5/15 = 1/3

1/3 = 1/3 É

c) (0, 2/5)

3x/5 + 2y/15 = 1/3

3(0)/5 + 2/15 . 2/5 = 1/3

0 + 4/75 = 1/3

4/75 = 1/3
