Question

for which equation is 1 by 3 a solution? ( a) 2/3+c =2/3 (b) 15x =3 (c)-1/6+w=1/6 (d) z/3=-1/9​

Answer 1

Answer:

d. z/3= -1/9

z= -1/9×3

z= -1/3

Answer 2

Step-by-step explanation:

Lets check step by step.

(a)2/3+c = 2/3

2/3+3c/3= 2/3

2+3c = 2 (when denominator are same they can be cancelled )

3c = 0

c =0

therefore no

b) 15x=3

x = 3/15

x= 1/5

therefore no

c) -1/6 + w = 1/6

-1/6 + 6w/6 = 1=6

-1 + 6w = 1 (when denominator are same they can be cancelled )

6w= 2

w = 2/6

w= 1/3.

therefore yes.

d) z/3= -1/9

z = -1/9×3

z=-1/3

therefore no
